In basketball, a technical foul (also informally known as a "T" or a "Tech") is any infraction of the rules penalized as a foul which does not involve physical contact during the course of play between players on the court, or is a foul by a non-player. The most common technical foul is for unsportsmanlike conduct. Technical fouls can be assessed against players, bench personnel, or even the entire team. They (along with their penalties) are more serious than a personal foul, but not as serious as a flagrant foul.

Technical fouls are handled slightly differently under international rules than under the rules used by the various competitions in the United States. First, illegal contact between players on the court is always a personal foul under international rules, whereas in the USA, such contact is (with some exceptions) a technical foul (rather than a personal foul) when the game clock is not running and/or when the ball is dead. Second, in FIBA play, players foul out after five total fouls, both technical and personal. The latter rule is similar to those in use in college, high school, and middle school basketball in the United States. However, in the NBA and WNBA, players are allowed six personal fouls before being disqualified, and technical fouls assessed against them do not count toward this total. However, unsportsmanlike technicals in the NBA carry a fine, its severity depending on the number of technicals the player has already obtained, and players are suspended for varying amounts of time after accumulating fifteen technicals in the regular season or seven in the playoffs.

In most American competitions, ejection of the offender (be he player, coach, or otherwise) is the penalty for being assessed two technical fouls in a game. In addition, any single flagrant technical foul, or a disqualifying foul in FIBA, incurs ejection. FIBA rules do not provide for ejection for any number of non-flagrant technicals against a player; however, two technicals on a coach or a third technical on the bench results in his ejection.
