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 show continues to air in syndication. The show is set around the 1860s and it centers on the wealthy Cartwright family, who live in the area of Virginia City, Nevada, bordering Lake Tahoe. The series stars Lorne Greene, Dan Blocker, Michael Landon, Pernell Roberts (who left after six seasons), and later David Canary and Mitch Vogel. The show is known for presenting moral dilemmas.

The title "Bonanza" is a term used by miners in regard to a large vein or deposit of ore, and commonly refers to the 1859 revelation of the discovery, not far from the fictional Ponderosa Ranch that the Cartwright family operated. The show's theme song itself, called "Bonanza," became a hit song in its own right. Only instrumental renditions, absent Ray Evan's words, were ever used during the series' long run.

In 2002, Bonanza was ranked No. 43 on TV Guide's 50 Greatest TV Shows of All Time, and in 2013 TV Guide included it in its list of The 60 Greatest Dramas of All Time. The time period for the television series is roughly between 1861 (Season 1) to 1867 (Season 13) during and shortly after the American Civil War.

During the summer of 1972, NBC aired reruns of episodes from the 1967–1970 period in prime time on Tuesday evening under the title Ponderosa.
