Whitemarsh was originally inhabited by the Lenni Lenape tribe of Native Americans. It was first settled by European colonists in 1683, as part of a tract of land purchased from William Penn by Major Jasper Farmar. Though Major Jasper Farmer died before making the voyage to his new land, his widow and family sailed, with servants, to Philadelphia in 1685. They established their homestead in Fort Washington. After the Widow Farmer died sometime in the 1690s, her son Edward began to sell 100 to 200 acre pieces of the township to Quakers and German immigrants.

In 1686, the discovery of limestone in Oreland in nearby Springfield and Upper Dublin townships, and subsequent discoveries of limestone in the township itself, drew settlers to Whitemarsh Whitemarsh Township was incorporated in 1704 as part of Philadelphia County and was one of the 28 original communities that comprised Montgomery County when it was created in 1784. The area in the 1600s and 1700s consisted of large English estates and its famous limestone quarries.

During the American Revolutionary War, both the Battle of White Marsh and the Battle of Barren Hill took place within the township.
