Playas de Tijuana (Spanish for "beaches of Tijuana") is the westernmost borough of the municipality of Tijuana, Baja California, stretching from the United States border in the north to Rosarito Beach Municipality in the south. The Bullring by the Sea was opened in 1960.

The current border between Baja California in Mexico and California in the United States was delineated in 1848. A marble monument was erected on the border near the shoreline in 1851.

The borough began to be developed in 1957 with the fraccionamientos of Soler and Costa Azul. The name "Playas de Tijuana" was acquired in 1959. The Bullring by the Sea was opened in 1960. Development continued through the 1980s.

The borough of Playas de Tijuana is located in the city of Tijuana, bordered by the Pacific Ocean to the west, the United States (California) to the north, the municipality of Playas de Rosarito to the south and the boroughs Centro to the Northeast and San Antonio de los Buenos to the East.

Playas de Tijuana borders the United States cities of Imperial Beach and San Diego, but there is no border crossing in the borough. In contrast to Playas de Tijuana, the Tijuana River Valley immediately north of the border remains rural and agricultural in character.

Its administration or government relies on a Municipal Delegate, or Delegado Municipal (in Spanish), who is appointed by the Municipal President of Tijuana.

The borough is in charge of the following services:

The Paseo Ensenada is a popular place for meeting and passing free time, and where major commercial centres and businesses are located. Plaza Coronado, which is located at the beginning of Paseo Ensenada, is the major entertainment centre, where mainly young people gather every day to spend free time. Water sports such as surfing, bodyboarding, and kayaking are available when ocean water quality is good—the water quality can be very bad soon after it rains. The Monumental bullring is located here as well as the Tijuana campus of the Universidad Iberoamericana.
