Macungie is derived from "Maguntsche", a place name used as early as 1730 to describe the region that is now Macungie and Emmaus, Pennsylvania. "Maguntsche" is a Lenape word, meaning either "bear swamp" or "feeding place of the bears". The borough's current seal depicts a bear coming to drink at water near some cattails. The Valentine Weaver House in Macungie was added to the National Register of Historic Places in 1984.
