John Kenneth Hilliard (October 1901 – March 21, 1989) was an American acoustical and electrical engineer who pioneered several important loudspeaker concepts and designs. He helped develop the practical use of recorded sound for film and won an Academy Award in 1935. Hilliard designed movie theater sound systems and worked on radar and submarine detection equipment during World War II. He collaborated with James B. "Jim" Lansing to create the long-lived Altec Voice of the Theatre speaker system.

Hilliard conducted research on high-intensity acoustics, vibration, miniaturization, and long-line communications for NASA and the U.S. Air Force. Toward the end of his career, he helped standardize noise-control criteria for home construction in California, a model that has since been applied to new homes throughout the United States.
