Richard Wagstaff Clark (November 30, 1929 – April 18, 2012) was an American television and radio personality and television producer who hosted American Bandstand from 1956 to 1989. He also hosted five incarnations of the Pyramid game show from 1973 to 1988 and Dick Clark's New Year's Rockin' Eve, which broadcast New Year's Eve celebrations in New York City's Times Square.

As host of American Bandstand, Clark introduced rock and roll to many Americans. The show gave many new music artists their first exposure to national audiences, including The Supremes, Ike & Tina Turner, Smokey Robinson and the Miracles, Stevie Wonder, Simon & Garfunkel, Iggy Pop, Prince, Talking Heads and Madonna. Episodes he hosted were among the first in which black people and white people performed on the same stage, and they were among the first in which the live studio audience sat down together without racial segregation. Singer Paul Anka claimed that Bandstand was responsible for creating a "youth culture". Due to his perennially youthful appearance and his largely teenaged audience of American Bandstand, Clark was often referred to as "America's oldest teenager" or "the world's oldest teenager".

In his off-stage roles, Clark served as chief executive officer of Dick Clark Productions (though he sold his financial interest in the company during his later years). He also founded the American Bandstand Diner, a restaurant chain themed after the television program of the same name. In 1973, he created and produced the annual American Music Awards show, similar to the Grammy Awards.

Clark was born on November 30, 1929, in Bronxville, New York, and raised in neighboring Mount Vernon, the second child of Richard Augustus Clark and Julia Fuller Clark, née Barnard. His only sibling, elder brother Bradley, a World War II P-47 Thunderbolt pilot, was killed in the Battle of the Bulge.

Clark attended Mount Vernon's A.B. Davis High School (later renamed A.B. Davis Middle School), where he was an average student. At the age of 10, Clark decided to pursue a career in radio. In pursuit of that goal, he attended Syracuse University, graduating in 1951 with a degree in advertising and a minor in radio. While at Syracuse, he was a member of Delta Kappa Epsilon fraternity (Phi Gamma).

In 1945, Clark began his career working in the mailroom at WRUN, an AM radio station in Utica, New York, that was owned by his uncle and managed by his father. Almost immediately, he was asked to fill in for the vacationing weatherman and, within a few months, he was announcing station breaks.

While attending Syracuse, Clark worked at WOLF-AM, then a country music station. After graduation, he returned to WRUN for a short time where he went by the name Dick Clay. After that, Clark got a job at the television station WKTV in Utica, New York. His first television-hosting job was on Cactus Dick and the Santa Fe Riders, a country-music program. He later replaced Robert Earle (who later hosted the GE College Bowl) as a newscaster.

In addition to his announcing duties on radio and television, Clark owned several radio stations. From 1964 to 1978, he owned KPRO (now KFOO) in Riverside, California under the name Progress Broadcasting. In 1967, he purchased KGUD-AM-FM (now KTMS and KTYD, respectively) in Santa Barbara, California.
