Papiss Cisse celebrates after his stunning strike against Chelsea
A superb double from Papiss Cisse secured Newcastle's first win at Stamford Bridge in 26 years to reinvigorate their surge for a Champions League place.
The Senegalese striker's sublime curling second late on followed a rifled volley and took his tally to 13 goals in 12 Newcastle games, reports the BBC.
Florent Malouda's glancing header was as close as Chelsea came.
They will hope for better in Saturday's FA Cup final against Liverpool.
And in the other game of the evening, Tottenham moved to within a point of third-placed Arsenal with a convincing victory at Bolton that keeps the Trotters inside the relegation zone.
Luka Modric put Spurs ahead with a fine dipping strike despite Bolton's claims that Sandro handled in the build-up.
The hosts, watched by Fabrice Muamba from the stands, equalised through Nigel Reo-Coker's first-time finish.
But Rafael van der Vaart slotted in before Emmanuel Adebayor sealed the points with two close-range efforts.
It was Tottenham's first away win in the Premier League since they beat Norwich at Carrow Road on 27 December.
They look firmly on course for a top-four finish and will hope to take six points from their final two matches, against Aston Villa and Fulham.
Bolton, by contrast, are fighting to stay in the division and Saturday's visit of West Brom now takes on even greater importance.
They are three points ahead of Blackburn and level on points with QPR, but Rangers have a far superior goal difference.
