Bad Education, Bluestone 42 and Some Girls have all been recommissioned by BBC Three.
The channel has also ordered new six-part sitcom 600 Days and comedy pilot Top Coppers.
BBC Three Controller Zai Bennett said: "BBC Three is at the heart of new comedy in the UK and is not only still on air, but thriving.
"These four deliciously different and brilliantly written series and pilot demonstrate our ongoing commitment to bring our viewers even more cutting edge, exciting and most importantly of all, funny, comedy this year."
Jack Whitehall's Bad Education will return for a third series in the autumn, while Bluestone 42 and Some Girls will also be back at a later date.
It was confirmed earlier this month that BBC Three is to close as a broadcast channel in late 2015, with much of its programming expected to shift to iPlayer.
