Since 1950, Haddon Township has been governed under the Walsh Act with a governing body comprised of a three-member commission. The Township is one of 30 municipalities (of the 565) statewide governed under the commission form of government. Commission members are elected at-large on a non-partisan basis as part of the May municipal election to serve four-year concurrent terms of office. At a reorganization meeting held after the election, each commissioner is assigned responsibility for supervising a specific department. The commissioners select one of their members to serve as a part-time mayor, who presides over meetings but has no independent executive function. Haddon Township has had only three mayors in its history: William Rohrer, William J. Park. Jr., (1997 New Jersey State League of Municipalities Mayors Hall of Fame), and Randall Teague.
