Motherwell slumped to a seventh Premiership game without a win as a Kevin Nisbet hat-trick earned Hibs all three points at Fir Park.
The Scotland striker gave the visitors the lead 16 minutes into the first half and netted either side of Stuart McKinstry's second-half strike to secure all three points.
Ross Tierney provided a nervy finish for Hibs as he bagged another goal inside the last minute, reducing the deficit to just one.
