The 1973 New Brunswick electoral redistribution was the most radical redistribution of electoral districts in the history of New Brunswick, Canada. Under this redistribution, New Brunswick changed from a mixture of multi-member districts and single-member districts to a scheme of only single-member districts, from bloc voting electoral system to first past the post. As the number of members per district had been re-evaluated as recently as 1967, the number of members was not changed, and multi-member districts were simply subdivided to form single-member districts.
