Wilson M. Tigard arrived in the area known as East Butte in 1852, and the community was renamed Tigardville in 1886 before the railroad renamed it Tigard in 1907 to distinguish it from nearby Wilsonville.

The arrival of the Oregon Electric Railway in 1910 triggered the development of Main Street and pushed Tigardville from a small farming community toward growth that led to its incorporation as a city in 1961.
