The 51-year-old actor, best known for featuring in alternative comedy shows in the 1990s, is writing and starring in six 30-minute episodes of the format, which will contain songs and special guests.
It's Kevin will be produced by the BBC in-house comedy team behind the BAFTA-winning Stewart Lee's Comedy Vehicle, in which he has appeared for sketches.
Cheryl Taylor, controller of comedy commissioning, said: "Kevin Eldon is a very special comedian indeed and we're delighted to have the opportunity to showcase his many talents on BBC Two."
Eldon said: "I have always liked chaffinches. The money I may receive from this show may well allow me buy more pictures of chaffinches."
The star collaborated with Chris Morris in Brass Eye, Jam and movie Four Lions, Lee and Richard Herring in Fist of Fun, and also played laughing racist Mike Sampson in the first series of I'm Alan Partridge.
It's Kevin with Kevin Eldon, to be screened in the early months of 2013, will be produced by Richard Webb.
