Colonel Bonny Serrano Avenue (also spelled Boni Serrano Avenue), formerly named and still referred to as Santolan Road, is a major east–west thoroughfare in the Eastern Manila District of Metro Manila, Philippines, running between San Juan and Quezon City. It forms the northern limit of San Juan and the southern limit of Quezon City's New Manila and Cubao districts and links the Philippine National Police headquarters in Camp Crame with the Armed Forces of the Philippines headquarters in Camp Aguinaldo. The avenue runs from the border of barangays Corazón de Jesús, St. Joseph (Halo-Halo), Pasadena, and Little Baguio in San Juan in the west to barangays Libís and Blue Ridge B near Quezon City's border with Marikina in the east. It was named after the decorated Korean War hero, Venancio "Bonny" Serrano. The four-lane avenue begins as a continuation of Pinaglabanan Street at P. Guevarra Street in the Corazon De Jesus area of San Juan. It proceeds due east and runs through the boundary between barangays Bagong Lipunan ng Crame in Quezon City and West Crame in San Juan, passing through the San Juan Municipal Cemetery before arriving at the northern side of Camp Crame. East of the Epifanio de los Santos Avenue junction, the avenue runs the northern boundary of Camp Aguinaldo with the barangays Socorro, San Roque, and Bayanihan, and intersecting with 15th Avenue at Camp Aguinaldo Gate 1.
