Lupton Stadium, Baseball stadium in Fort Worth, US

Lupton Stadium is a baseball facility in Fort Worth with a two-tiered design that provides seating for thousands of spectators. The complex features luxury suites, press areas, locker rooms for both teams, and dedicated training spaces for players.

Lupton Stadium opened on February 2, 2003, replacing the TCU Diamond, which had served as the Horned Frogs' home from 1962 to 2002. The original $7 million complex was built with two tiers, three suites, offices, two radio booths, a press box, a ticket office, and home and visiting team locker rooms. In 2010, a $1 million project expanded upper-deck seating to raise capacity to 9,000 and added an auxiliary scoreboard along the first base line.

The ballpark's name honours Charlie and Marie Lupton, and the field itself is called Williams-Reilly Field. Attendance has risen from about 1,500 fans per game in 2003 to over 4,000, ranking in the top 15 nationally for NCAA home games since 2011 and leading all private schools in total and average attendance in 2015.

The playing surface is Bermuda TIFF 419, and the dugouts are heated with MLB-style bat and helmet racks. Home and visitor bullpens sit outside the field of play; the home bullpen was moved beyond the left-center field fence in 2014–15. Partially shaded party patios in the right field corner can be reserved, and fans may bring food and beverages, including beer and wine.

The record crowd of 8,994 filled the grounds in 2023, when TCU hosted Indiana State in an NCAA Super Regional and each of the three games drew more than 8,000. Attendance has ranked in the national top 15 since 2011, and in 2015 the Horned Frogs led all private schools in total and average attendance.
