The Iglesia Ni Cristo Locale of F. Manalo-San Juan (Filipino: Lokal ng F. Manalo-San Juan), formerly Locale of Riverside (Filipino: Lokal ng Riverside) is a chapel and former central office complex of the Philippine-based Christian sect, Iglesia ni Cristo.

Located in Barangay Santa Lucia, San Juan, it was completed in 1952, and it is the former central office complex and main house of worship of the church.

The art-deco ensembles were designed by the national artist of architecture Juan Nakpil, who also built some of the standalone theaters in Rizal Avenue, UP Diliman Campus buildings and Quiapo Church.

The church administration was searching for a suitable location for the central office for the growing Iglesia ni Cristo under the leadership of Felix Y. Manalo.

Currently It is one of the oldest Locale Congregations of Metro Manila East and one of the Church's two Worship Buildings in the City of San Juan.
