Trinity Lutheran Church is a historic church in Atkins, Arkansas. It is located east of Winrock and north of Petit Jean State Park, on the east side of Montgomery Trace (County Highway 5). It is a wooden plank-framed structure, with a weatherboard exterior, gabled roof, and cut fieldstone foundation. Its front facade is unadorned except for the entrance, which is simply framed, and the sides each have three sash windows. The interior has original finishes and simple hand-hewn pews. The church was built in 1886, and is one of the oldest Lutheran churches in Arkansas.
