John Stiles Collins (December 29, 1837 – February 11, 1928) was an American Quaker farmer from Moorestown, New Jersey who moved to South Florida at the turn of the 20th century.

Although the farming venture was not successful, with involvement from his family, including his sons and sons-in law, John S. Collins also became a land developer.

The Collins Bridge project ran short of funds and the 2.5 mile (4 km) long wooden toll bridge was in danger of not being completed when 74-year-old Collins struck a deal with automotive pioneer and millionaire Carl G. Fisher (1874–1939) to loan him the needed funds in exchange for 200 acres (800,000 m2) of land.

The Collins Bridge was located at the southern terminus of promoter Fisher's Dixie Highway project, which brought traffic from the mid-west as part of the National Auto Trail road system.

Collins, his family, and Fisher all became very wealthy with the development of Miami Beach, which had a 400% increase in resident population between 1920 and 1925.
