Bonanza is an NBC television western series that ran from 1959 to 1973. Lasting 14 seasons and 431 episodes, "Bonanza" is NBC's longest-running western, and ranks overall as the second-longest-running western series on U.S. network television (behind CBS's "Gunsmoke"), and within the top 10 longest-running, live-action American series.

The series initially starred Lorne Greene, Pernell Roberts, Dan Blocker, and Michael Landon and later featured (at various times) Guy Williams, David Canary, Mitch Vogel, and Tim Matheson. The show is known for presenting pressing moral dilemmas.
