Left-arm quick David Payne took 4-23 and spinner Ollie Price 3-32, as the Bears could muster only 124-9 in reply.
Gloucester snatch last Finals Day spot
Cameron Bancroft had top-scored for Gloucestershire with 43 in 35 balls, while opening partner Miles Hammond made 30 from 24.
The Bears' New Zealand seamer Zak Foulkes took 3-22, spinners Danny Briggs and Dan Mousley picking up two wickets each and George Garton executing two magnificent run-outs with direct hits.
The Bears were 37-2 after the powerplay, with Payne having Alex Davies caught on the square-leg boundary and Moeen Ali caught behind for 27.
The Bears struggled to regain their momentum, losing Mousley leg before to an attempted pull and Jacob Bethell caught at extra cover, both wickets falling to Price.
Price's off-spin claimed a third victim as Sam Hain unleashed a towering hit on the leg side but failed to clear Hammond on the mid-wicket boundary.
Chris Benjamin hammered six off Tom Smith and Garton took two fours off Price to ease the pressure but then Josh Shaw ramped it up again with two wickets in two balls as Garton holed out to long-off and Foulkes perished leg-before.
It all came down to 18 required off the last six balls, with Payne conceding just three and adding the wickets of Benjamin and Jake Lintott for good measure.
