The Altoona Mountain Citys were a professional baseball franchise that played in Altoona, Pennsylvania in 1884. The Mountain Citys were a charter member of the Union Association, but folded after 25 games with a 6–19 record. They were alternately known as the Ottawas, after the local history of the Ottawa people in the 17th and 18th centuries. At the start of the season, they were also known by the nickname Altoona Pride, and were advertised as the Famous Altoonas. By the season's end, they were known as the Altoona Unfortunates.
