Mansfield Street (officially in French: '''rue Mansfield''') is a north–south commercial street located in Downtown Montreal, Quebec, Canada. It is situated two blocks from Peel Street and links Sherbrooke Street in the north to Saint-Antoine Street in the south.
Constructed around 1845 by James Smith and Duncan Fisher, Mansfield Street was named for William Murray, 1st Earl of Mansfield (1705-1793), a Lord Chief Justice of the King's Bench.
