Museo Tin Marin, Children's museum in San Salvador, El Salvador.

Museo Tin Marin is a children's museum in San Salvador offering interactive spaces where young visitors explore science, the environment, culture, and creative expression. The exhibitions encourage learning through hands-on activities and direct engagement with the displayed materials.

The museum opened in 1999 as a dedicated educational space for children to learn through interactive experiences. This founding created an important venue for hands-on discovery in the city.

The museum's name comes from the chorus of a well-known Salvadoran children's song, "Tin Marín de dos pingüé", which children sing while choosing players for a game. The playful reference matches the institution's stated method of "learning by playing", applied across its 32 interactive exhibitions on science, art, communication, health and the environment.

The museum sits beside Parque Cuscatlán in San Salvador, managed by the Asociación Museo de los Niños. It receives about 188,000 visitors a year, so school groups can fill the halls on weekday mornings. The 32 permanent and temporary exhibitions are spread across five educational areas, so allow time to move between them.

The museum has 32 permanent exhibitions across five educational areas: science and technology, art and culture, communication and expression, health and prevention, and environment. One of them, "Mi Cuerpo Me Pertenece a Mí", is described as the only exhibition in the region addressing the prevention of abuse.
