Dubuque YMCA Building, also known as the Iowa Inn, is a historic building located in Dubuque, Iowa, United States. Several area churches partnered to form the local YMCA in 1857. It was one of the first chapters formed west of the Mississippi River. Its activities ceased during the American Civil War, and it was reformed in 1866. They rented rooms on Main Street for their activities. Its first modest gymnasium was outfitted in 1884, and it was improved in 1992 when YMCA took over the facilities over the former Dubuque Athletic Club. The local YMCA completed the first section of this facility two years later, with the second section completed in 1916.
