However, the defeat means that Gloucester finish third in the table despite having the same won five, lost one record as Northampton and Leicester - bonus points proving to be the difference.
The hosts started well, but Gloucester slowly gained ascendancy. Plenty of chances were created, and the Northampton line was crossed twice but tries were ruled out for a knock on and a short lineout called not straight.
Northampton then scored the game's only try as they took advantage of a handling error.
Gloucester managed several line breaks, and hit the post with a penalty. They kept going right until the very end and were held up over the line with the last play of the game.
The team now progress to the play off stage, and will play London Irish next Monday.
