Miguel Angel Lotina will be coaching the struggling club until the end of the season.
The experienced specialist became the third coach of the Spanish team this season, replacing Juan Carlos Garrido in December and losing his job after a weekend defeat to the Levante team.
In the league table, Villarreal, who have lost four out of their last five matches, are only in 17th place, even though they secured a spot in the Champions League last season.
