The Allen House is a historic building located in Dyersville, Iowa, United States.

Allen was a land speculator and developer who had this house built in 1857, which was the peak year for building in Dyersville.

It features a low-pitched hip roof, broad eaves without brackets, Federal influenced metal lintels on each window, a transom above the main doorway, and nearly full-sized front porch with heavy square wood posts.

A two-story wing was added onto the back in the early 20th-century, and a carriage house was built about the same time.
