Goals from Robert Snodgrass, Ross McCormack and Luciano Becchio saw Leeds defeat 10-man Ipswich and move to within a point of the play-off zone.
Ipswich opened the scoring with Andy Drury finding the bottom corner of the net from 20 yards for the visitors.
Keeper Alex McCarthy was red carded for handling outside his area before Snodgrass levelled from close range.
Leeds took the lead when McCormack tapped into an empty net before Becchio's third from a tight angle.
The visitors took a deserved lead when Lee Martin played the ball across the penalty area from the left and Drury swept the ball into the bottom corner from 20 yards.
McCarthy did not make his first save until turning away Leeds defender Zac Thompson's cross on the hour. But Leeds were handed their first gift 10 minutes later when Ipswich were reduced to 10 men.
Ipswich's keeper handled the ball outside his penalty area following a hopeful punt forward and three minutes later replacement keeper Arran Lee-Barrett was picking the ball out of his net.
Leeds substitute Aidan White crossed the ball from the right and Ibrahima Sonko, under pressure in the six-yard box, could only play the ball to Snodgrass, who duly converted.
Another mistake from Ipswich, this time from Lee-Barrett, handed Leeds their second goal.
Adam Clayton crossed from the right and McCormack took advantage of Lee-Barrett's indecision to pinch the ball and roll it into an empty net.
Becchio stole in to add a third from a tight angle after Smith had failed to clear the danger in time added on.
