Kilsyth was an electoral district of the Legislative Assembly in the Australian state of Victoria.
It was contested at that election by Liberal MP Lorraine Elliott, whose nearby electorate of Mooroolbark had been abolished in the redistribution.
Elliott was not expected to face a serious challenge at the election, but amidst a statewide Labor landslide, was defeated in a major upset by Labor candidate Dympna Beard.
Beard's narrow victory left Kilsyth as one of the most marginal seats in the state, and she faced an extremely close race at the 2006 election.
The final result was not known for several days, with Liberal candidate David Hodgett eventually being declared the victor by 185 votes.
