Ronald Ulysses Swanson is a fictional character portrayed by Nick Offerman in the political satire sitcom Parks and Recreation. The character was created by Michael Schur and Greg Daniels with inspiration from a real-life Libertarian elected official. Offerman provided creative input, and aspects of his own personality were folded into the character. Despite the creators' intentions, NBC was initially reluctant to cast Offerman in the role, until the network finally agreed five months later.
