The Harrison was an American automobile built in Grand Rapids, Michigan originally by the Harrison Wagon Company from 1905 through 1906.

The Harrison grew to be a large vehicle, eventually having a wheelbase of 10 ft (3.0 m).

The 1906 and 1907 models featured a self-starting system which introduced acetylene into the proper cylinder for starting 'on the spark'.

The cars came with a four-cylinder engine of 6.3L in capacity, with overhead valves.
