Exhibit 5.01

[LETTERHEAD OF CORNING INCORPORATED]

April 24, 2026

To the Board of Directors

Corning Incorporated

Ladies and Gentlemen:

As Vice President and Corporate Secretary of Corning Incorporated (the “Company”), I am furnishing this opinion in connection with the preparation and filing with the Securities and Exchange Commission (the “Commission”) of a Registration Statement on Form S-3 (as amended, the “Registration Statement”), including a base prospectus (the “Base Prospectus”), which provides that it will be supplemented by one or more prospectus supplements (each such prospectus supplement, together with the Base Prospectus, a “Prospectus”), under the Securities Act of 1933, as amended (the “Securities Act”), relating to the registration under the Securities Act and the proposed issuance and sale from time to time pursuant to Rule 415 under the Securities Act, together or separately and in one or more series (if applicable) of: (i) the Company’s debt securities (the “Debt Securities”), (ii) shares of the Company’s preferred stock, par value $100 per share (the “Preferred Shares”), which may be represented by depositary shares (the “Depositary Shares”), (iii) shares of the Company’s common stock, par value $0.50 per share (the “Common Shares”), and (iv) warrants to purchase Debt Securities, Preferred Shares, Depositary Shares or Common Shares (the “Warrants” and, together with the Debt Securities, Preferred Shares, Depositary Shares and Common Shares, the “Securities”). Any Debt Securities and Preferred Shares may be convertible into or exchangeable for Common Shares or other securities or property.

The Debt Securities may be issued in one or more series pursuant to an indenture, dated as of November 8, 2000 (the “Base Indenture”), between the Company and The Bank of New York Mellon Trust Company, N.A. (successor to J. P. Morgan Chase & Co., formerly The Chase Manhattan Bank) (the “Trustee”), the form of which is incorporated by reference to Exhibit 4.01 to the Registration Statement, and one or more board resolutions, supplements thereto or officers’ certificates thereunder (such indenture, together with the applicable board resolution, supplement or officers’ certificate pertaining to the applicable series of Debt Securities, the “Applicable Indenture”). Each series of Preferred Shares will be issued pursuant to a certificate of amendment to the Company’s Restated Certificate of Incorporation, dated April 27, 2012, as amended (the “Restated Certificate of Incorporation”) stating the number, designations, relative rights, preferences and limitations of the shares of such series as established by resolution of the Company’s Board of Directors (each, a “Certificate of Designations”). The Warrants will be issued under one or more warrant agreements (each, a “Warrant Agreement”) to be entered into between the Company and a financial institution identified therein as warrant agent (each, a “Warrant Agent”). The Depositary Shares will be issued under one or more deposit agreements (each, a “Deposit Agreement”) to be entered into between the Company and a financial institution identified therein as depositary.

This opinion is being furnished in connection with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act, and no opinion is expressed herein as to any matter pertaining to the contents of the Registration Statement or related applicable Prospectus, other than as expressly stated herein with respect to the issue of the Securities.

In connection with the opinions expressed below, I have examined the resolutions of the Board of Directors of the Company authorizing the issuance, offering and sale of the Securities (the “Resolutions”). I have also examined the originals or copies identified to my satisfaction of such corporate records of the Company; such other agreements and instruments, certificates of public officials and officers of the Company; and such other documents as I have considered necessary for the purposes hereof.

In my examination, I have assumed the genuineness of all signatures, the authenticity of all documents submitted to me as original documents, the conformity to original documents of all documents submitted to me as

copies, the legal capacity of natural persons, and the legal power and authority of all persons signing on behalf of the parties to all documents (other than the Company).

On the basis of the foregoing and such examination of law as I have deemed necessary, and subject to the assumptions and qualifications set forth in this letter, I am of the opinion that:

The opinions set forth above are subject to: (i) the effect of bankruptcy, insolvency, reorganization, fraudulent transfer, moratorium or other similar laws relating to or affecting the rights and remedies of creditors; (ii) (a) the effect of general principles of equity, whether considered in a proceeding in equity or at law (including the possible unavailability of specific performance or injunctive relief), (b) concepts of materiality, reasonableness, good faith and fair dealing, and (c) the discretion of the court before which a proceeding is brought; and (iii) the invalidity under certain circumstances under law or court decisions of provisions providing for the indemnification of or contribution to a party with respect to a liability where such indemnification or contribution is contrary to public policy. I express no opinion as to (a) any provision for liquidated damages, default interest, late charges, monetary penalties, make-whole premiums or other economic remedies to the extent such provisions are deemed to constitute a penalty, (b) consents to, or restrictions upon, governing law, jurisdiction, venue, arbitration, remedies, or judicial relief, (c) waivers of rights or defenses, (d) any provision requiring the payment of attorneys’ fees, where such payment is contrary to law or public policy, (e) any provision permitting, upon acceleration of any Debt Securities, collection of that portion of the stated principal amount thereof which might be determined to constitute unearned interest thereon, (f) the creation, validity, attachment, perfection, or priority of any lien or security interest, (g) advance waivers of claims, defenses, rights granted by law, or notice, opportunity for hearing, evidentiary requirements, statutes of limitation, trial by jury or at law, or other procedural rights, (h) waivers of broadly or vaguely stated rights, (i) provisions for exclusivity, election or cumulation of rights or remedies, (j) provisions authorizing or validating conclusive or discretionary determinations, (k) grants of setoff rights, (l) proxies, powers and trusts, (m) provisions prohibiting, restricting, or requiring consent to assignment or transfer of any right or property, (n) any provision to the extent it requires that a claim with respect to a security denominated in other than U.S. dollars (or a judgment in respect of such a claim) be converted into U.S. dollars at a rate of exchange at a particular date, to the extent applicable law otherwise provides, and (o) the severability, if invalid, of provisions to the foregoing effect.

With your consent, I have assumed (a) that each of the Debt Securities, Depositary Shares, Warrants, Applicable Indenture, Deposit Agreements and Warrant Agreements governing such Securities (collectively, the “Documents”) will be governed by the internal laws of the State of New York, (b) that, except to the extent I have expressly opined as to such matters with respect to the Company herein, each of the Documents has been or will be duly authorized, executed and delivered by the parties thereto, (c) that each of the Documents constitutes or will constitute legally valid and binding obligations of the parties thereto other than the Company, enforceable against each of them in accordance with their respective terms, and (d) that the status of each of the Documents as legally valid and binding obligations of the parties will not be affected by any (i) breaches of, or defaults under, agreements or instruments, (ii) violations of statutes, rules, regulations or court or governmental orders, or (iii) failures to obtain required consents, approvals or authorizations from, or to make required registrations, declarations or filings with, governmental authorities.

The foregoing opinions assume that (i) the Registration Statement shall have become effective under the Securities Act and will continue to be effective, (ii) the Applicable Indenture has been qualified pursuant to the Trust Indenture Act of 1939 to the extent so required, and (iii) at the time of the issuance and delivery of any Security, the Resolutions related thereto will not have been modified or rescinded.

My opinion is limited to matters governed by the Federal laws of the United States of America and the laws of the State of New York.

I hereby consent to the use of this opinion as an exhibit to the Registration Statement and to the use of my name under the heading “Validity of Securities” in the related prospectus. In giving such consent, I do not thereby admit I am in the category of persons whose consent is required under Section 7 of the Securities Act.
