The Lovell House or Lovell Health House is an International style modernist residence designed and built by Richard Neutra between 1927 and 1929. The home, located at 4616 Dundee Drive in the Los Feliz neighborhood of Los Angeles, California, was built for the physician and naturopath Philip Lovell. It is considered a major monument in architectural history, and was a turning point in Neutra's career.

The International Style or internationalism is a major architectural style that was developed in the 1920s and 1930s and was closely related to modernism and modernist architecture. It was first defined by Museum of Modern Art curators Henry-Russell Hitchcock and Philip Johnson in 1932, based on works of architecture from the 1920s. The terms rationalist architecture and modern movement are often used interchangeably with International Style, although the former is mostly used in the English-speaking world to specifically refer to the Italian rationalism, or even the International Style that developed in Europe as a whole.
