The United Protestant Church, also known as The Church of a Thousand Trees, is a historic church located at the corner of South Denali Street and East Elmwood Avenue in Palmer, Alaska. Formerly a non-denominational Protestant church, it is now a Presbyterian church, and still holds services today. It is a rustic log two-story structure, in the shape of a cross. A small bell tower with a dormer roof rises just above the main entrance. The interior is shaped from rustic log elements, with carved pews. The church property includes a manse and garage, built from similar materials.
The church was listed on the National Register of Historic Places in 1980.
