A crowd of 36,405 descended on LS11 but Marcelo Bielsa's side squandered some fine chances to put the game to bed before falling to a 1-0 defeat.
Leeds were undone in the 75th minute as Jonjo Shelvey's low free-kick from the edge of the area sailed through the Whites box and past Illan Meslier with the help of a slight touch from Magpies substitute Ciaran Clark from close range.
The travelling Toon Army were seeing their side win in the league for only the second time this season, Newcastle bringing themselves seven points behind the Whites who stayed 15th, seven points clear of the drop zone.
Here are 12 pictures of United's fans in the packed stands from YEP photographer Jonathan Gawthorpe and an interesting Magpies spectator at the end.
