Re:        Becton, Dickinson and Company 2004 Employee and Director Equity-Based
Compensation Plan, as amended and restated as of January 27, 2026,
Form S-8 Registration Statement Under the Securities Act of 1933, as amended

Ladies and Gentlemen:

As Chief Securities and Governance Counsel, Corporate Secretary of Becton, Dickinson and Company (the “Company”), I am familiar with all corporate action taken by the Company to authorize for issuance an additional 5,237,485 shares of Common Stock, par value $1.00 (the “Common Stock”), under the Company’s 2004 Employee and Director Equity-Based Compensation Plan, as amended and restated as of January 27, 2026 (the “Plan”).

On the basis of the foregoing, it is my opinion that the Company has taken all necessary and appropriate corporate action in connection with the authorization for issuance of shares of Common Stock thereunder, and that the shares of Common Stock covered by the above-referenced registration statement, when issued and sold in the manner referred to in the Plan, will constitute legally issued, fully paid and non-assessable shares of Common Stock of the Company.

This opinion is rendered to you solely in connection with the above matter. This opinion may not be relied upon by you for any other purpose, or relied upon by or furnished to any other person, without my prior written consent.

I consent to the filing of this opinion as Exhibit 5.1 to the above-captioned Registration Statement.

Very truly yours,

/s/ Stephanie M. Kelly
