The following is a list of mayors of Ottawa. Until 1854, Ottawa was known as Bytown. Over the course of Ottawa's history, the borders of the municipality have greatly expanded through annexations. This most recently occurred in 2001 when a number of neighbouring communities were amalgamated with Ottawa.
When the city of Ottawa amalgamated in 2001, these were the mayors of the municipalities that amalgamated:
