Bagong Silang, also known as Barangay 176, was a barangay located in Caloocan, Metro Manila, Philippines. It existed from 1971 until its official division in 2024 and was situated within the city's Zone 15. The area spanned a land area of 574 hectares.
The barangay was notable for being the most populous barangay in the Philippines, recording a population of 261,729 during the 2020 census. Due to this high population density, the area underwent a division following a plebiscite held on August 31, 2024. It was split into six distinct barangays: 176-A, 176-B, 176-C, 176-D, 176-E, and 176-F, although the region is still informally referred to as Bagong Silang.
