The Legislative District of San Juan City is the representation of the San Juan City in the Philippine House of Representatives. From 1907 to 1972 it was represented as part of the first district of Rizal. It was part of the representation of Region IV in the Interim Batasang Pambansa from 1978 to 1984. It was grouped with Mandaluyong from 1984 to 1995 for representation in the Regular Batasang Pambansa and the restored House of Representatives, as the district of San Juan-Mandaluyong. The two were separated and granted their own representations in Congress by virtue of section 49 of Mandaluyong's city charter (Republic Act No. 7675) which was approved on February 9, 1994, and ratified on April 10, 1994.
