Olsen Field at Blue Bell Park, Baseball stadium in College Station, Texas.

Olsen Field at Blue Bell Park is a baseball stadium in College Station, Texas, home of the Texas A&M Aggies. After the 2011–2012 renovation it seats 5,400, down from 7,000, with standing room for over 7,000. The rebuilt facility added an expanded concourse and concessions area, luxury suites, a new press box, club seating, two grass berms, expanded locker rooms and coaches offices, and a student athletic center.

Olsen Field was dedicated on March 21, 1978, and named for C. E. "Pat" Olsen, a 1923 Texas A&M graduate who had played in the New York Yankees minor league system. It hosted its first NCAA Regional in 1989 and has been a regional site five times. A renovation begun on June 7, 2011, funded partly by the owners of Blue Bell Creameries, brought naming rights and reopened the field on February 17, 2012.

The stadium is home to the Texas A&M Aggies baseball program. In 2015 the Aggies ranked seventh among Division I programs in attendance, averaging 4,857 per home game, and the 1999 NCAA regional drew 53,287 over the tournament, second among that year's regionals.

The stadium sits on the Texas A&M campus in College Station, about 2.5 km north of the city centre. Seating is split between fixed seats and two grass berms, so standing-room spots push capacity past 7,000. The 2011–2012 renovation added an expanded concourse and concessions area, luxury suites, club seating and a new press box.

The post-renovation attendance record of 8,075 was set on April 13, 2024, when Texas A&M beat Vanderbilt 9-0. The figure surpassed the previous mark from the 1999 NCAA regional, when 53,287 spectators attended across the whole tournament.
