Casino Alemán, Historic monument in San Juan district, Mexico City, Mexico.

Casino Alemán occupies a building at 23 López Street in the San Juan neighborhood of Mexico City's historic center. The late-19th-century structure was remodeled in the early 20th century and inaugurated as the casino's headquarters on December 31, 1907. It previously housed the 6th police station and offered a cantina, billiard room, 6,000-book library, bowling alley, theater and dance hall, and reception rooms.

The Casino Alemán was founded on 11 June 1848 by German expatriates inspired by the 1848 revolutions in Europe. After occupying two houses on today's Francisco I. Madero street, it moved in 1907 to the former 6th police station at López 23, inaugurated on 31 December 1907. In 1943 the Mexican government confiscated the building under wartime enemy-property laws.

The building served as a meeting place for German-speaking residents who gathered here for social events and celebrations. This role shaped how people understood the site as a community space within the city.

The building stands at 23 López Street in the San Juan neighbourhood of the historic centre, in the Cuauhtémoc borough. It is reached on foot from the surrounding streets of the centro histórico. The entrance is on López Street, a short walk from the Madero corridor where the institution's first two premises stood.

A marble statue of the naturalist Alexander von Humboldt was sent as a gift during Mexico's independence centennial celebrations in 1910. This offering symbolized the connections between European and Mexican elites during that period.
