The 1867 Ontario general election was the first general election held in the newly created Province of Ontario, Canada. Previously, the territory was known as Canada West, a part of the Province of Canada. The election was held on September 3, 1867, to elect the 82 members of the 1st Legislative Assembly (MLAs). The dates of the election in 1867 varied from August 20 to September 26.

The 1st Parliament of Ontario was in session from September 3, 1867, until February 25, 1871, just prior to the 1871 general election. This was the first session of the Legislature after Confederation succeeding the Legislative Assembly of the Province of Canada. The 1867 general election produced a tie between the Conservative Party led by John Sandfield Macdonald and the Liberal Party led by Archibald McKellar. Macdonald led a coalition government with the support of moderate Liberals.
