The Zhaishan Tunnel (Chinese: 翟山坑道; pinyin: Zháishān Kēngdào; Pe̍h-ōe-jī: Chú-soaⁿ Khiⁿ-tō) is a tunnel in Jincheng Township, Kinmen County, Taiwan.

Construction of the tunnel started in 1961 and was completed on 22 March 1966, a few years after the Second Taiwan Strait Crisis in 1958 between the Republic of China Armed Forces and People's Liberation Army.

Due to the lack of manpower and money to maintain the tunnel, it was closed and abandoned in 1986.

Later on, there was growing interest in preserving the national heritage and remembering those who fought for Kinmen, thus on 23 May 1997, the Kinmen National Park took over the management of the tunnel.
