The 2019 season was the Houston Texans' 18th in the National Football League (NFL) and their sixth under head coach Bill O'Brien. It also marked the first full season without the ownership of Bob McNair, who died during the 2018 season. It was, however, the first season of full ownership of both Janice McNair and D. Cal McNair. For the first time in franchise history, the team played in London, against the Jacksonville Jaguars. On June 7, 2019, the Texans fired general manager Brian Gaine after only one season.

The Houston Texans are a professional American football team based in Houston. The Texans compete in the National Football League as a member club of the American Football Conference (AFC) South division, and play their home games at NRG Stadium.
