The Texas A&M Aggies baseball team represents Texas A&M University in NCAA Division I college baseball. The Aggies have competed in the Southeastern Conference since 2013. The Aggies play home games at Olsen Field at Blue Bell Park. The team was the 2024 runner-up in the Men's College World Series Final, losing in a closely contested three-game series to Tennessee.

Texas A&M baseball has compiled an all-time record of 2,550–1,427–42 (.634 winning percentage) through the 2014 season. The Aggies have won 20 conference championships (15 in the Southwest Conference, four in the Big 12, and one in the SEC). Texas A&M has made 33 NCAA tournament appearances, advancing to the College World Series eight times, in 1951, 1964, 1993, 1999, 2011, 2017, 2022, and 2024. The Aggies have never won a national championship in baseball. Texas A&M's long, rich history and tradition in baseball began in 1894. After a decade break, the program returned in 1904 and has competed every year since. With over 2,700 all-time victories, the Aggies rank second in all-time wins among SEC programs.

Baseball is among the first organized sports played at Texas A&M, and what was then A&M College of Texas fielded its first club in 1879. The first games were played between members of Company A and Company B of the Corps of Cadets. It's not surprising baseball started so early, considering that Texas A&M and Major League Baseball were both founded in 1876, and it was one of America's most popular sports of the period. The team played many of its earliest games against Galveston, Bryan, Baylor, Navasota, and Calvert. Games were limited by what town could be reached by train or horse. Most of the teams didn't have uniforms or even a real field. The same train tracks that run by Olsen Field today used to carry the team to its games. By 1907, the Cincinnati Reds had stopped off in College Station and beat A&M 9–0, scoring all 9 runs in the third inning, when, "our boys went to pieces." Seventeen head coaches led A&M baseball from 1904 to 1958, including football coaches Charley Moran, Dana X. Bible, and Homer Norton. During this period, A&M finished with a 626–469–27 record (.572 winning percentage), claimed seven Southwest Conference titles, and made their first trip to the College World Series in 1951. In 1951, led by Beau Bell, the Aggies won a three-game series in the District VI playoffs over Arizona and advanced to the College World Series. In the 1951 College World Series, Texas A&M defeated Ohio State 3–2 in a lower first-round elimination game to give the Aggies their first College World Series win.

Tom Chandler came to Texas A&M as an assistant to head coach Beau Bell in 1958. He took over as head coach in 1959 and immediately won the Southwest Conference championship in his first year. Over the next 25 years at the helm, Chandler led the Aggies to four more conference championships, eight NCAA postseasons, and an appearance in the 1964 College World Series. His teams finished 660–329–10 (.667 winning percentage). Chandler was honored for his accomplishments by being inducted into the American Association of Baseball Coaches Hall of Fame. His jersey is now displayed on the left-field wall at Olsen Field in recognition of his contributions. Tom Chandler was born on March 19, 1925, in Greenville, Texas. He attended Dallas public schools and graduated from Adamson High School in 1943. He then attended Arkansas A&M for two years in the Marine V-12 program. In 1946, he graduated from the Marine Corps Officers School. He served as a member of the Marine Corps Honor Guard that presented the colors at the funeral of President Franklin D. Roosevelt in April 1945.

Mark Johnson, an assistant under Chandler, assumed head-coaching duties in 1985 and guided the program for just over two decades. During that time, his teams put together a win–loss record of 876–431–3 (.670 winning percentage) and made College World Series appearances in 1993 and 1999. Johnson's highly ranked teams and powerful offenses in the late 1980s and throughout the 1990s brought excitement and increased attendance to Olsen Field. His #7 jersey hangs on the right-field wall at Olsen Field in honor of his service to A&M. Johnson's 876 wins are the most in Texas A&M history. Johnson led the Aggies to a 37–29 (.561) postseason record in 13 appearances.

In 1989, the Aggies put together a 58–7 record (17–4 in SWC play) and were SWC co-champions. The Aggies won the SWC tournament and hosted a regional at Olsen Field, which included Jackson State, BYU, South Alabama, and number-12 LSU. The Aggies exploded in the first three games, outscoring their opponents 65–13 before they were upset by LSU twice, ending one of the most remarkable seasons in A&M history. Despite not advancing to the College World Series, the Aggies finished the year number two overall in the final Baseball America poll (behind Wichita State, winner of the CWS). The Aggies defeated number-three Texas four out of five times (with two wins coming on walk-off home runs), including twice in the SWC tournament.

Johnson led the Aggies to the College World Series in 1993. The Aggies won the Southwest Conference championship and swept through the Central I Regional in College Station (defeating Yale, Lamar, UCLA, and North Carolina) at Olsen Field to advance to Omaha for the third time. A&M defeated Kansas, 5–1, for the second CWS win in A&M history. Notable stars on the team included Jeff Granger (who holds the single-game strikeout record at A&M with 21), Brian Thomas, Chris Clemons, Trey Moore, and Kelly Wunsch.

The Aggies again advanced to the College World Series in 1999, led by Daylan Holt, Steven Truitt, John Scheschuk, Dell Lindsey,Casey Fossum and Luke Cicalese. In the College Station regional, the Aggies lost to Long Beach State in game 2 before defeating Ole Miss and Long Beach State twice to advance to the super regionals, where they faced number-17 Clemson. The Aggies defeated Clemson in a best of three series, 2–1, earning the team's fourth trip to the College World Series.
