The agency beat ZenithOptimedia and Brilliant to the work, which was previously held by the Carat-owned Feathers Brookbank.
Peter Thomson, a director at Manning Gottlieb OMD, said: "It's always satisfying to be appointed by a client that gets exposure to so many media agencies, and which is so knowledgeable about our sector."
Manning Gottlieb OMD will plan and buy media for the radio station's through-the-line relaunch campaign, which is set to go live in the spring.
The relaunch of the station follows its acquistion by Guardian Media Group for £44.5m in June. GMG aims to reposition Jazz FM and broaden its appeal.
"Jazz FM was looking for an agency to persuade non-listeners to re-evaluate the brand," Thomson said.
The £2m creative work for the relaunch was awarded to Kitcatt Nohr Alexander Shaw in January. This will include corporate identity, a new strategy and through-the-line creative. The new-look station is expected to lose its chameleon logo, which has been part of its identity for the last five years.
Since GMG took over, Jazz FM has appointed a raft of new presenters including jazz pianist Ramsey Lewis.
