Alfeo Brum (22 March 1898 – 25 February 1972) was an Uruguayan politician and lawyer.

His brother Alfeo was with him at the time he committed suicide, and from that moment on he was considered an opponent and an outlaw to Terra's regime.

The Brum brothers were followers of the orthodox "Batllismo" faction within the Colorado Party (at the time, the followers of the ideals of President José Batlle y Ordoñez).

The death of President Tomás Berreta, and the succession to the presidency of Luis Batlle Berres, determined that Alfeo Brum, the first Senator of the Batllismo faction's Senate list, took over the Vice-Presidency for the rest of the period, until March 1951.

Martínez Trueba and the Colorado Party won the elections, and Alfeo Brum went on to serve as vice president from 1951 to 1952.
