Adrian David Houser (born February 2, 1993) is an American professional baseball pitcher for the New York Mets of Major League Baseball (MLB). He has previously played in MLB for the Milwaukee Brewers.

Amateur career
Houser attended Locust Grove High School in Locust Grove, Oklahoma. He committed to attend the University of Oklahoma to play college baseball for the Oklahoma Sooners baseball team.

Houston Astros
The Houston Astros of Major League Baseball (MLB) selected Houser in the second round, with the 69th overall selection, of the 2011 MLB Draft. Houser signed a contract with Houston three days after he was drafted and was subsequently assigned to the Rookie-level Gulf Coast League (GCL) Astros. After six GCL games in which he went 1–2 with a 4.03 ERA and 25 strikeouts, the Astros organization promoted Houser to the Greeneville Astros of the Appalachian League, their other Rookie ball team. Between the two teams, Houser went 2–4 in his first season of professional baseball, with a 4.31 ERA and 44 strikeouts in 12 games and 48 innings pitched. Houser spent the entire 2012 season with Greeneville as well, going 3–4 in 11 starts with a 4.19 ERA and 54 strikeouts in 58 innings.

Houser spent 2013 with the Tri-City ValleyCats where he pitched to an 0–4 record and a 3.42 ERA in 14 games (nine starts), and 2014 with the Quad Cities River Bandits where he went 5–6 with a 4.14 ERA in 25 games, 17 being starts. He started 2015 with the Lancaster JetHawks and was promoted to the Corpus Christi Hooks.

Milwaukee Brewers
On July 30, 2015, the Astros traded Houser, along with Brett Phillips, Domingo Santana and Josh Hader, to the Milwaukee Brewers for Carlos Gómez and Mike Fiers. Milwaukee assigned him to the Biloxi Shuckers. In 26 games (20 starts) between Lancaster, Corpus Christi and Biloxi, he compiled a 7–5 record with a 4.43 ERA.

Houser was promoted to Milwaukee for the annual September call-ups. He made his major league debut on September 26, 2015. In 2016, Houser spent all of the season with Biloxi, going 3–7 with a 5.25 ERA in 13 starts. Houser's 2017 season was limited due to injury, and he pitched only 17.2 innings all season. He began 2018 with Biloxi.

Houser was recalled to the Brewers' major league roster on June 17, 2018, and pitched the team's game against the Philadelphia Phillies later that day. He vomited twice on the mound during that game. This would be the first of several occurrences where Houser vomited during a game. On August 11, 2019, in a game against the Texas Rangers, Houser misfielded a ground ball hit at him by Elvis Andrus. Shortly after, Houser walked towards the back of the mound, where he vomited, the second such time Houser had vomited on the mound during a game. After this, he proceeded to notch ten strikeouts and finish the game as the winning pitcher. In 2019 for Milwaukee, Houser appeared in 35 games, pitching to a 6–7 record and a 3.72 ERA with 117 strikeouts in 111.1 innings pitched. In 2020, Houser recorded a 5.30 ERA and 1-6 record with 44 strikeouts in 56.0 innings of work across 12 games.

On April 27, 2021, Houser hit his first major league home run off of Daniel Castano of the Miami Marlins. In a game against the Marlins on May 8, Houser hit his second career home run, also off of Castano. 2021 was a productive year for Houser. He appeared in 28 games and made 26 starts. Houser finished the season with a 3.22 ERA. Houser also tossed his first complete-game shutout against the Cardinals on September 4, 2021. Houser's salary for the 2022 season was decided via the arbitration process; he had asked for $3 million, and received $2.425 million. In 2022 he was 6-10	with a 4.73 ERA, and had the lowest LOB percentage in the majors (60.8%).

On November 18, 2022, Houser signed a one-year, $3.6 million contract with the Brewers, avoiding arbitration. In 2023, Houser appeared in 23 games, most of which were starts, and posted a 8-5 record and 4.12 ERA.

New York Mets
On December 20, 2023, the Brewers traded Houser and Tyrone Taylor to the New York Mets in exchange for Coleman Crow.
