The Cessna Citation Columbus (Model 850) is the latest extension by Cessna of its Citation family of business jets. Unveiled on February 6, 2008, development of the largest Citation was first revealed at the 2006 National Business Aviation Association convention as the Large Cabin Concept, or LCC. The Columbus has a target range of 4000nm with 8 passengers. Cessna will partner with Spirit AeroSystems for the fuselage, Pratt & Whitney Canada will provide power with a pair of PW810 turbofan engines, and Rockwell Collins is to provide avionics.

The mock-up of the cabin was first shown at the Paris Air Show in 2007.

On 29 April 2009 Cessna announced that it was suspending the Citation Columbus program. The program may be restarted once economic conditions improve. The company indicated that it will lay off 1,600 workers, including up to 700 workers from the Columbus program.
