The Puerta de los Leones (Spanish: Lions Gateway) is the main entrance to the first section of the Chapultepec Park, in Mexico City.

Immediately, it connects with the Lions Garden, a green area that was originally part of the San Miguel Chapultepec town, and whose main parish was set there.

It is connected to the 1975 Bridge of the Lions (which crosses Circuito Interior) and reaches the Altar a la Patria.

It was named after the two lion bronze sculptures that lie on granite Art Deco plinths; the mineral came from Germany, Canada and Zacatecas.

Visitors access through an iron gate with a relief of an eagle with its wings outstretched that is located on the ground floor.
