The Manitoba Legislature is the legislature of the province of Manitoba, Canada. Today, the legislature is made of two elements: the lieutenant governor and the unicameral assembly called the Legislative Assembly of Manitoba. The legislature has existed since Manitoba was formed out of part of Rupert's Land in 1870.

The Legislative Assembly of Manitoba is the deliberative assembly of the Manitoba Legislature in the Canadian province of Manitoba. Fifty-seven members are elected to this assembly at provincial general elections, all in single-member constituencies with first-past-the-post voting. Bills passed by the Legislative Assembly are given royal assent by the lieutenant governor of Manitoba in the name of the King of Canada. The Manitoba Legislative Building is located in central Winnipeg.
