The 2007 NCAA Division I baseball tournament was held from June 1 to 24, 2007. Sixty-four NCAA Division I college baseball teams advanced to the post season tournament after having played through a regular season, and for some, a conference tournament.

The 2007 tournament culminated with 8 teams advancing to the College World Series at historic Rosenblatt Stadium in Omaha, Nebraska, on June 15. Unseeded Oregon State repeated as national champions, winning all five of its games in the 2007 CWS.

Oregon State went undefeated through the College World Series, posting a 5–0 record. The Beavers, led by head coach Pat Casey, won all three games in their four-team bracket and then, for the second straight season, defeated North Carolina in the best-of-three championship series— this time in two games. Oregon State became the fifth team to win consecutive NCAA titles (last done by LSU in 1996-97), and were the first team to win four games in a CWS by six or more runs. As of 2019, 2007 Oregon State remains the only team to have ever won at least four games by six or more runs in the same College World Series. Their opener against Cal State Fullerton was a tight 3–2 victory, but OSU's last four games in the CWS were not close, impressive for a team seeded in the lower half of the 64-team tournament.

The Beavers also became the first team to win the CWS after having posted a losing conference record. Oregon State was a disappointing 10–14 (.417) in the Pac-10, placing sixth among the nine baseball-playing schools (Oregon dropped baseball in 1981, but revived it in 2009.)

However, the Beavers' non-conference record during the regular season was an impressive 28–3 (.903), and as defending NCAA champions, just enough to gain a berth in the 64-team tournament. They were placed as a No. 3 seed in one of the 16 four-team regionals, in Charlottesville, Virginia. Oregon State responded by going 11–1 (.917) in the post season. Oregon State won their final 10 games to finish at 49–18 (.731) overall. The Beavers trailed in only one inning of 2007 CWS: the first inning of the final game. Their only loss in the post season came during the second game of regionals, where they fell in 13 innings to host Virginia.^[1]

Oregon State freshman pitcher Jorge Reyes (of Warden, Washington) was named the Most Outstanding Player of the 2007 CWS. Reyes was 2–0 as a starter, defeating Cal State Fullerton in the opener and North Carolina in the first game of the finals.

Two elite programs from Louisiana, LSU and Tulane both failed to qualify for the field of 64, marking the first time since 1984 both schools stayed home. LSU reached the College World Series 13 times between 1986 and 2004, winning five national championships (1991, 1993, 1996, 1997, 2000), while Tulane made trips to the CWS in 2001 and 2005.

Conference champions from 30 Division I conferences earned automatic bids to regionals. The remaining 34 spots were awarded to schools as at-large invitees.
