小开曼（Little Cayman）是开曼群岛的三个岛屿中面积最小、人口最稀少的岛屿，位在加勒比海，距离大开曼岛东北方约87英里、开曼布拉克西方约5英里。

历史上关于小开曼岛最早的纪录可追溯至1503年5月10日、欧洲首位发现美洲大陆的航海家克里斯多福·哥伦布第四、五次出航时，当时其船队因强风而被迫偏离航道，当时他见到此处有许多海龟而将这座岛屿命名为「Las Tortugas」（西班牙文：海龟），后来该岛才因为岛上有鳄鱼而更名为「Las Caymanas」（西班牙文：鳄鱼）。自从这座岛被发现之后，直到今天仍由岛上稀少的居民继续经营下去。

Little Cayman is one of three islands comprising the Cayman Islands. It is located in the Caribbean Sea, approximately 60 miles northeast of Grand Cayman and five miles (8 km) west of Cayman Brac. Little Cayman is by far the least populous, with a permanent population of about 170. It is about 10 miles (16 km) long with an average width of 1 mile (2 km) and most of the island is undeveloped. Almost the entire island is at sea level. The highest elevation is about 40 feet (12 metres).
