Lanterman House is a bungalow-style historic house museum in La Cañada Flintridge, California on the National Register of Historic Places. The house was commissioned by Dr. Roy Lanterman in 1915 and was built by A. L. Haley (b. 1865), who was a prominent builder of both residences and commercial buildings in the Los Angeles area.

Lanterman, who had treated victims of the 1906 San Francisco earthquake and fire, insisted that the foundation, floors and walls of his house be built from reinforced concrete, and Haley interpreted the aesthetics of Craftsman-style wood-built bungalows in the new material. The house retains much of its original furniture and finishes, including a grand ballroom that occupies the entire second floor, and Dr. Lanterman's consulting rooms in the basement.
