The Former Marine Police Headquarters Compound (Chinese: 前水警總部; Jyutping: cin4 seoi2 ging2 zung2 bou6), constructed in 1884, is located in Tsim Sha Tsui, Kowloon, Hong Kong. The site is now officially renamed as 1881 Heritage.

The Kowloon compound used to be occupied by the Marine Police, now a unit within the Hong Kong Police Force, since its establishment until late 1996, when it was moved to Sai Wan Ho.
