The 1897 Washington Senators baseball team finished the season with a 61–71 record, tied for sixth place in the National League. The Senators (also known as the Nationals) finished in the first division in the only time in the franchise's nine-year run in the National League. After getting off to a dismal 31–55 start, Washington won 30 of its last 46 games. Their overall winning percentage (.462) would be the high-water mark for this franchise before it folded in contraction at the conclusion of the 1899 season.
