Mayfaire by-the-Lake is a juried, fine arts festival held on the shores of Lake Morton in downtown Lakeland, Florida. This two-day, free community festival, traditionally held on Mother's Day weekend, is a premier fine arts festival in Florida.

Begun as a crafts fair on the lawn of the Lakeland Public Library, Mayfaire by-the-Lake, coordinated by the Polk Museum of Art at Florida Southern College, has grown into one of Florida’s premier outdoor art festivals. Held on Mother’s Day weekend each year, Mayfaire is located on the shores of beautiful Lake Morton in downtown Lakeland, Florida. Artists set up on the grass on one side of the lake only. Mayfaire is one of the largest and oldest outdoor art festivals in Central Florida.
