Lynde Phelps Wheeler (July 27, 1874 – February 1, 1959) was an American physicist and engineer.
He was born in Bridgeport, Connecticut and was educated at Yale University, where he received a Ph.D. in physics in 1902, with a thesis on "The Reflection of Polarized Light from Mercury in Water."
He remained at Yale as a professor in the physics department until 1926, when he joined the Radio Division of the United States Naval Research Laboratory.
He retired from the FCC in 1946 and became a consultant for the private firm Pickard and Burns, Inc., in Needham, Massachusetts.
In addition to his research in optics, electricity, and radio, Wheeler published a biography of his mentor at Yale, mathematical physicist J. Willard Gibbs.
