The 1893 major league baseball season began on April 27, 1893. The regular season ended on September 30, with the Boston Beaneaters as the pennant winner of the National League and therefore winner of the final Dauvray Cup.
The 1893 season saw no postseason championship series, unlike the split-season 1892 World's Championship Series. This would not last, as the following season would see the Temple Cup, which would be a championship series between the NL pennant winner and the runner-up.
The 1893 schedule consisted of 132 games for the twelve teams of the National League. Each team was scheduled to play 12 games against the other eleven teams in the league. This replaced the 154-game, 14-games-each format put in place in the previous season and would be used until .

The ballpark for the Louisville Colonels, Eclipse Park was largely destroyed in a fire towards the end of the previous season, though the team continued to play in its remains. In the 1893 season, the Colonels played only one home game on May 4 at the still destroyed ballpark. They would move one block south at a new ballpark, also named Eclipse Park, when they returned home for their next home game on May 22.
When the World's Columbian Exposition in Chicago opened in May, the Chicago Colts wanted to break with their no-Sundays tradition and start playing Sunday games to attract Fair visitors, but their South Side Park lease forbade Sunday ball. They sought a new location, which turned out to be West Side Park. After drawing well on their two May Sunday games, the club abandoned their three-season tenure at South Side Park after only eight games (their last being on May 24) and moved to the West Side on a full-time basis from their next home game on Sunday, June 18.
