Hoàn Kiếm Lake (Vietnamese: Hồ Hoàn Kiếm, chữ Hán: 湖還劍, meaning "Lake of the Returned Sword" or "Lake of the Restored Sword"), also known as Sword Lake (Hồ Gươm) or Tả Vọng Lake (Hồ Tả Vọng), is a fresh water lake, measuring some 12 ha in the historical center of Hanoi, the capital city of Vietnam.
In the past, the lake was variously named "Lục Thủy Lake" (Vietnamese: Hồ Lục Thủy, meaning "Green Water Lake" - aptly named for the water's color) or "Thủy Quân Lake" (Vietnamese: Hồ Thủy Quân, meaning "Mariner's Lake"). The lake is one of the major scenic spots in the city and serves as a focal point for its public life.
