Chris Iwelumo's moment of magic proved the difference between the sides as Bristol City saw off fellow strugglers Crystal Palace at Selhurst Park.
The striker, on loan from Wolves, struck a stunning volley on the turn from inside the area 17 minutes from time to settle a dour encounter.
Jamal Campbell-Ryce came close to a second but an out-of-sorts Palace could not muster a response at the other end.
The defeat leaves Palace outside the drop zone on goal difference alone.
