Colombo Town Guard was a regiment attached to the Ceylon Defence Force which was the predecessor to the Sri Lanka Army prior to 1949 when the Ceylon Army was formed.
Members of the regiment included many personalities who became important figures in Sri Lankan history.
In 1915 during the Sinhalese-Moor Riots the Town Guard was called to restore public order with authorization to summarily execute anyone they deemed to be a rioter during the 100-day long period of martial law in the colony.
In 2006 due to the Sri Lankan Civil War the Sri Lankan Government announced a formation of a Home Guard unit made up of residents of Colombo for deployments within the city.
This was not a reforming of the town guard as the new unit came under the authority of the Department of Civil Defence (Sri Lanka) unlike the town guard that came under the command of the army.
