Rudd, 45, will appear in two episodes of the drama in January, reported Entertainment Weekly.
"He's the world's nicest human being - and the funniest," 'Parks and Recreation' executive producer Michael Schur said about Rudd.
"We made a list of all the people that we wanted to have back and he was high on the list, so we managed to snag him. Bobby will come back into the fold when Ben (Adam Scott) needs to fill a certain position and he thinks Bobby might be a good candidate," he added.
