Located 16 miles (26 km) from Philadelphia, it consists of the villages of Gulph Mills, King of Prussia, Swedeland, Swedesburg, and portions of Radnor, and Wayne.
The westernmost part of the township comprises the largest part of the 1,300-acre (5 km2) Valley Forge National Historical Park. The township is the home of the King of Prussia mall, the third-largest shopping mall in the United States in terms of gross leasable area.

The name Merion originates with the county of Merioneth in north Wales. Merioneth is an English-language translation of the Welsh Meirionnydd, itself named after Meirchion (or Meirion), grandson of Cunedda Wledig (b. ca. 380 A.D.), King of North Wales.[3]
