Mildred E. Mathias Botanical Garden, Botanical garden at University of California, Los Angeles, United States.

The Mildred E. Mathias Botanical Garden is a botanical garden on the campus of the University of California, Los Angeles. The hilly grounds hold a collection of tropical trees, East Asian plants, and Australian species arranged in dedicated sections across a series of winding paths.

The garden was established in 1929 alongside the opening of the UCLA campus and received its first state funding in 1933 through a work relief program. That early support helped shape the first planted areas of what would become a teaching collection.

The garden is named after Mildred E. Mathias, a botanist who taught and worked at UCLA for decades. Visitors today can see interpretive signs acknowledging the land as the traditional territory of the Gabrielino/Tongva peoples.

The garden sits within the UCLA campus and can be reached on foot from several campus entrances. The grounds are hilly with uneven paths, so sturdy footwear is a good idea before exploring.

The dawn redwood here was planted in 1948, shortly after living Metasequoia glyptostroboides were found in western China; the species had been known only from fossils. It ranks among the tallest dawn redwoods in North America. The garden's Torrey pine is one of the largest known.
