The 1999 Victorian state election, held on Saturday, 18 September 1999, was for the 54th Parliament of Victoria. It was held in the Australian state of Victoria to elect the 88 members of the state's Legislative Assembly and 22 members of the 44-member Legislative Council. The Liberal–National Coalition led by Jeff Kennett and Pat McNamara, which had held majority government since the 1996 election, lost 15 seats and its majority due mainly to a swing against it in rural and regional Victoria.

The Victorian Liberal Party, officially known as the Liberal Party of Australia (Victorian Division) and branded as Liberal Victoria, is the state division of the Liberal Party of Australia in Victoria. It was formed in 1944. It became the Liberal and Country Party (LCP) in 1949, and simplified its name to the Liberal Party in 1965. The party sits on the centre-right to right-wing of the Australian political spectrum.
