Leonardo Balagot Perez (November 22, 1925 – June 16, 2007) was a Filipino politician who served as a member of the Philippine House of Representatives on behalf of the province of Nueva Vizcaya.

During his congressional career, he served as Chairman of the Committees on Anti-Filipino Activities, and Privileges and Election Law and authored Republic Act 4735, which established the municipality of Ambaguio from the provincial capital of Bayombong, in 1966.

[6] Perez joined Marcos' cabinet from 1981 to 1984 as Presidential Adviser on Political Affairs and was therefore a concurrent member of the Interim Batasang Pambansa.

In 1984, he was elected to the Regular Batasang Pambansa representing Nueva Vizcaya after a bitterly disputed campaign marred by allegations of fraud.

In 1987, Perez ran again for the Senate as a candidate of Marcos' Kilusang Bagong Lipunan party in elections held in May[8] but lost.

[citation needed] Perez' brother, Benjamin, served as Congressman of Nueva Vizcaya from 1969 to 1972 and was elected as an Assemblyman for Region II (Cagayan Valley) in the Interim Batasang Pambansa from 1978 to 1984.
