Pedro Guevara y Valenzuela (February 23, 1879 – January 19, 1938), was a Filipino soldier, lawyer, legislator, and Spanish-language writer who became Resident Commissioner of the Philippines during the American occupation.

Guevara joined the Filipino forces during the Philippine Revolution and assisted in promoting the peace agreement of the Biak na Bato at San Miguel, Bulacan, in 1897.

He gave up his Senate seat in 1923, less than two years before his second term expired, as he was elected as a Nationalist resident commissioner to the House of Representatives of the United States Congress.

During this time, Guevara worked tirelessly for the approval of the Tydings–McDuffie Act, which would establish the Commonwealth of the Philippines and eventually its independence in 10 years.

His term ended on February 14, 1936, when a successor qualified in accordance with the newly established Commonwealth of the Philippines was selected.
