Mary Jane's Mishap; or, Don't Fool with the Paraffin is a 1903 British silent comic trick film, directed by George Albert Smith, depicting disaster after housemaid Mary Jane uses paraffin to light the kitchen stove.

The film, according to Michael Brooke of BFI Screenonline, "is an example of Smith's interest in cinematic effects - including, here, the use of superimposition to suggest ghosts," which, "is notable for its then sophisticated mix of wide establishing shots and medium close-ups," and, "also contains two wipes to denote a change of scene."
