Tijuana is a city in Northwestern Mexico. It is located in Baja California State at 32.53N, 117.02W. In 2003 it had an estimated population of 1,270,600 people.

This border city just south of San Diego, California is sometimes considered a mix of Mexico's good and bad: known for its historical sites, legendary bullfighting arenas, beautiful beaches, popular discos and shopping areas, Tijuana is also considered to be Mexico's biggest illicit drug and prostitution center.

The famous battle between the Tijuana Cartel and rival Juarez Cartel was portrayed in the 2000 Hollywood movie Traffic.

Tijuana's International Airport (General Abelardo L. Rodriguez International Airport) is served by Mexicana, Aeromexico, and Aero California. The airport is known for the spectacular approaches the airplanes have to carry out before landing, as they have to fly just over a fence before landing. That same fence separates Tijuana from San Diego.
