The 1955 NCAA Baseball Tournament was played at the end of the 1955 NCAA baseball season to determine the national champion of college baseball. The tournament concluded with eight teams competing in the College World Series, a double-elimination tournament in its ninth year. Eight regional districts sent representatives to the College World Series with preliminary rounds within each district serving to determine each representative. These events would later become known as regionals. Each district had its own format for selecting teams, resulting in 25 teams participating in the tournament at the conclusion of their regular season, and in some cases, after a conference tournament. The College World Series was held in Omaha, NE from June 10 to June 16. The ninth tournament's champion was Wake Forest, coached by Taylor Sanford.
