The Stagecoach Inn of Chappell Hill (also known as the Stage Coach Inn) is a historic stagecoach inn at Main and Chestnut Streets in Chappell Hill, Texas. It was built in 1850 by Mary Elizabeth Haller (née Hargrove), the founder of Chappell Hill. Mary and her husband Jacob Haller (d. 1853), the town's first postmaster, built the stately 14-room Greek Revival inn along the road from Houston to Austin, where some of Texas' first stagecoach lines, the Smith and Jones, and later the F.P. Sawyers, would stop for the night. Prior to the building's use as a stagecoach stop, it served as a boarding house for students attending college in Chappell Hill. At that time it was called Hargrove House or Hargrove House Hotel.
