Goals from Ashley Barnes and Michael Kightly sparked a Turf Moor promotion party as Burnley secured Premier League football for next season.
The Clarets knew before kick-off that victory would see them bounce back into the top flight, having been outside the elite since their 2010 relegation.
And they were taking no chances, starting the game brightly with Barnes (22) putting them ahead with a close-range volley before Kightly (43) whipped in a free-kick which evaded everyone and flew into the top corner.
Wigan improved after the break but the outcome was never in doubt and Burnley's fans were left to celebrate, invading the pitch, as their team guaranteed a top-two finish.
Play-off bound Derby pushed Barnsley closer to the Championship drop-zone with a 2-1 victory at the iPro Stadium.
A glaring error by goalkeeper Luke Steele allowed Jeff Hendrick to put the Rams ahead before a deflected Johnny Russell shot increased their lead and, although Nick Proschwitz pulled a goal back, it came too late for the visitors.
Russell had a chance to extend the hosts' advantage with a penalty eight minutes from the end, but saw it saved by Steele.
Charlie Austin netted a late winner as QPR guaranteed a play-off spot after a 2-1 victory over Watford at Loftus Road.
Trailing to Mathias Ranegie's goal six minutes into the second half, Rangers laboured before Joey Barton's 76th-minute free-kick hauled them level.
And top scorer Austin, badly missed during a recent two-month spell out with a shoulder injury, gloriously curled home his 16th goal of the season in the closing stages to clinch a 2-1 victory.
It left Watford's hopes of a top-six finish in the Sky Bet Championship looking remote, although they have a game in hand on most of their rivals.
Two goals from Matt Derbyshire kept Nottingham Forest's play-off hopes alive as they beat Leeds 2-0 at Elland Road on Monday.
Derbyshire has only started six games this season but his Saturday goal against Birmingham ended Forest's 13-match winless run and the former Blackburn striker's rich vein of form continued at a subdued Elland Road.
With a visit to Bournemouth and a home task against Brighton to come, Forest are just one point outside the top six after winning 2-0 in West Yorkshire.

Bournemouth twice fought back from behind to draw 2-2 with Ipswich, a result that keeps both sides in the play-off hunt.
Seventh-placed Ipswich twice led in front of their biggest crowd of the season at Portman Road thanks to goals from Paul Anderson and Paul Green, but they were pegged back, first by brilliance and then by good fortune.
Steve Cook's amazing overhead kick ensured parity at the interval and Ritchie made it a point apiece when his 20-yard free-kick was deflected off Cole Skuse and wrong-footed Dean Gerken.
