The Gen. George Stark House is a historic house at 22 Concord Street in Nashua, New Hampshire. The 2-1/2 story wood frame house, built in 1856, is one New Hampshire's finest Italianate houses. It was built by George Stark, a Manchester native and civil engineer who worked on railroad projects across northern New England. He became superintendent of the Nashua and Lowell Railroad in 1857. Design inspiration for the house came from Andrew Jackson Downing's works. The house was used for many years of the 20th century by the local congregation of the Church of Christ, Scientist.
