Bellmawr was authorized to incorporate as a borough on March 23, 1926, from portions of the now-defunct Centre Township, and was made independent based on the results of a referendum held on April 21, 1926. The boroughs of Mount Ephraim, Runnemede and Lawnside were also created in the same two-day period. The borough was named for Ernest C. Bell, who owned a farm in the area.
