Vegas (stylized as Vega$) is an American crime drama television series starring Robert Urich that aired on ABC from September 20, 1978, to June 3, 1981, with the pilot episode airing April 25, 1978. Vegas was produced by Aaron Spelling and was created by Michael Mann. The series (with the exception of special episodes filmed in Hawaii and San Francisco) was filmed in its entirety on location in Las Vegas, Nevada.

Urich stars as private detective Dan Tanna, who drives to his detective assignments around the streets of Las Vegas in a flashy red 1957 Ford Thunderbird convertible. (The 1957 red T-Bird replaced a 1967 yellow Chevrolet Corvette that was Tanna's car in the pilot episode, a car which ended up being destroyed by fire.) Working for a wide variety of Las Vegas clients, the detective work included locating missing persons, helping solve various Las Vegas hotel and casino crimes, solving casino chip and money scams, and working to make Las Vegas a safer place for residents and tourists alike. Dan Tanna makes a point of not accepting divorce cases, or working as a bodyguard. Being in Las Vegas, Tanna is occasionally hired to work for well-known celebrity clients who have issues regarding their personal safety, and need help solving personal issues or threats against them.
