Enes Unal came off the bench to score two late goals for Villarreal, denying Atletico Madrid victory and dealing Diego Simeone's men a huge blow in LaLiga's title race.
Antoine Griezmann's controversial penalty had Atletico on track for a 12th win in 13 games in all competitions, the striker scoring from 12 yards at Estadio de la Ceramica after he was harshly adjudged to be brought down by Jaume Costa.
Jan Oblak had been mostly untested in the Atletico goal but when Alvaro Gonzalez stood up a fine right-wing cross to the back post, Unal was there to nod home a deserved leveller for Villarreal with eight minutes to go.
And in the first minute of added time, Turkey international Unal tucked home at the back post, Daniele Bonera's cross having made its way through a crowded box to find the unmarked striker.
Griezmann had earlier wasted a golden opportunity to secure all three points for Atletico - now 11 points behind Barcelona - the LaLiga leaders having eased to a comfortable 2-0 win at home to Athletic Bilbao earlier on Sunday.
Atleti are winless in their last six league meetings with Villarreal and their title hopes, having been hurt by a narrow loss at Camp Nou earlier this month, now look over as Atleti imploded, Vitolo's stoppage-time red card compounding their misery.
Saul forced a first-minute save from Sergio Asenjo as Atletico made a rapid start.
Griezmann then collected a booking for fouling Roberto Soriano, which means the striker will be available for next month's derby with rivals Real Madrid after serving a one-game ban.
Villarreal had been on top but after Griezmann went down under Jaume Costa's clumsy challenge in the box, Atletico took the lead in the 20th minute.
Griezmann sent Asenjo the wrong way from 12 yards after a long delay, Villarreal's players claiming the France international deceived the officials.
Koke struck the post from Sime Vrsaljko's pullback as Atletico ran through the gears.
But at the other end Villarreal were close to levelling in the 31st minute, Pablo Fornals rifling narrowly wide after robbing Koke on the edge of the visitors' penalty area.

Villarreal continued to show attacking intent after the break, with Rodri influential in midfield, Mario Gaspar hitting a ferocious 25-yard drive that Oblak collected well on the bounce.
Penalty appeals for an apparent handball in the Atleti box were rejected before the interval and the referee said no again when Jose Gimenez seemed to drag Carlos Bacca to the ground.
Griezmann should have wrapped up the points in the 70th minute when Diego Costa and Angel Correa combined to set up the striker, but he blazed his shot well over the crossbar and was whistled off by the home fans when Simeone substituted him.
That miss came back to haunt Atletico in incredible fashion as Unal struck only eight minutes after his introduction, guiding home a fine header from Gonzalez's right-wing cross.
With Atletico stunned by the equaliser, worse was to come as Bonera's cross was not cleared, Unal finding himself in space to beat Oblak from close range.
Vitolo then saw red for clashing with Nicola Sansone as Simeone's men - beaten 3-0 at Villarreal last season - endured another miserable visit that left their title hopes in tatters.
