Boller and Chivens was an American manufacturer of high-quality telescopes and spectrographs headquartered in South Pasadena, California.

In the 1950s, Boller and Chivens collaborated with Perkin-Elmer to develop and manufacture the large-aperture Baker-Nunn satellite tracking camera for the United States Vanguard space satellite program.
A 41-cm (16-inch) Boller and Chivens Cassegrain reflector originally housed at the Harvard-Smithsonian Oak Ridge Observatory in Massachusetts is available for public use at the National Air and Space Museum's Public Observatory Project on the National Mall in Washington, D.C.
