William M. Kaula (May 19, 1926 – April 1, 2000) was an Australian-born American geophysicist and professor at the University of California, Los Angeles. Kaula was most notable for his contributions to geodesy, including using early satellites to produce maps of Earth's gravity. The National Academies Press called Kaula "the father of space-based geodesy". The Los Angeles Times called him "one of the leading planetary physicists of the last four decades".
