The Dobbin House Tavern, known also as Dobbin House, on 89 Steinwehr Avenue in Gettysburg, Pennsylvania is a tavern which is listed on the National Register of Historic Places. It was established in 1776, making it the oldest standing structure in Gettysburg. It was built to be a home for Reverend Alexander Dobbin and his family. The building may have been a first stop on the Underground Railroad north of the Mason–Dixon line, although this has not been substantiated.
