Cabo San Lucas, commonly called Cabo, is a city at the southern tip of the Baja California peninsula, in the municipality of Los Cabos in the Mexican state of Baja California Sur. As of the 2005 census, the population was 56,811 people. It is the largest community in Los Cabos municipality, and the second-largest in Baja California Sur, after La Paz.

Cabo is known for its sandy beaches, several world-class Scuba diving locations, balnearios and the distinctive sea arch El Arco de Cabo San Lucas. As a result, the Los Cabos Corridor has become a high-end holiday destination with a number of resorts and timeshares along the coast between San Lucas and San José del Cabo.

It is thought that the first humans came to the southern end of the peninsula 1,400 years ago. When the first Europeans arrived, they encountered nomadic groups of Pericú surviving on a subsistence diet based on the gathering of fruit, seeds, roots, and shellfish, as well as hunting and fishing. They lived a Neolithic lifestyle, without metals.
