Sayner is an unincorporated community in the town of Plum Lake in Vilas County, Wisconsin. It is located at the intersection of Highway 155 and County N, about 15 miles northwest of Eagle River.

Snowmobilers from neighboring Eagle River and St. Germain visit Sayner in the winter months. The Sayner Barnstormers handle the trails. Sayner is also home to one of the nation's oldest summer camps, Camp Highlands for Boys, founded in 1904, and located on the northeast end of Plum Lake. Located on the south shore of Plum Lake, the Plum Lake Golf Course is the oldest 9-hole golf course in the state of Wisconsin, founded in 1912.
