The Marine Engineers' Beneficial Association (MEBA) is the oldest maritime trade union in the United States still currently in existence, established in 1875. MEBA primarily represents licensed mariners, especially deck and engine officers working in the United States Merchant Marine aboard US-flagged vessels. It is a member union of the AFL–CIO.

MEBA officers work in both the oceans and the Great Lakes in many settings, including on container ships, tankers (including LNG carriers), cruise ships, drillships, tugboats and ferries, as well as in various capacities in the shoreside ship transport and marine industries and on government-contracted ships of the US Maritime Administration's Ready Reserve Force and US Navy's Military Sealift Command. Merchant mariners deliver critical defense cargo to United States armed forces in times of military conflict.

Members and their families benefit from MEBA's collective bargaining agreements through the union's Medical Plan, 401(k) Plan, Pension Trust, and Vacation Plan.
