Sweat Spire is a 7,580-foot-elevation (2,310 meter) summit located in the Olympic Mountains, in Jefferson County of Washington state.

The nearest higher peak is Mount Johnson, 0.06 mi (0.097 km) to the southwest, and Gasp Pinnacle (7,520 ft) is to the immediate north.

The first ascent of the 200-foot-tall spire was made in 1962 by Hilton Keith, Joel Merkel, Joe Munson, and Jim Parolini.

Sweat Spire is located in the marine west coast climate zone of western North America.

As fronts approach, they are forced upward by the peaks (orographic lift), causing them to drop their moisture in the form of rain or snow.
