Longgan Lake (simplified Chinese: 龙感湖; traditional Chinese: 龍感湖; pinyin: Lónggǎn Hú) is a freshwater lake in central China, divided between Susong County of Anhui Province and Huangmei County at the eastern extremity of Hubei Province. The lake is situated near the north bank of the middle reaches of Yangtze River, opposite Poyang Lake (which is south of the Yangtze). The lake was named Longgan Lake in a 1955 decision which combined the names of two former lakes, Long Lake (龙湖) and Gan Lake (感湖).
As of 1998, the lake's water surface area was 316.2 square kilometres (100 sq mi). It is an important marsh protective area. Longgan Lake is an important aquatic farming area.
