The flag of Laos (Lao: ທຸງຊາດລາວ; thungsad Lāo) consists of three horizontal stripes, with the middle stripe in blue being twice the height of the top and bottom red stripes. In the middle is a white disc, the diameter of the disc is 4⁄5 the height of the blue stripe. The flag ratio is 2:3.

The flag was first adopted in 1945 under the short-lived Lao Issara government of 1945–46, then by the Pathet Lao. It is one of the two flags of a country currently governed by a communist party (the other being Cuba) that currently does not use any communist symbolism. The current flag was adopted on December 2, 1975, when it became a socialist state. The royal flag before 1975 remains in use by a number of Laotian diaspora.
