Reginald Claypoole Vanderbilt (January 14, 1880 – September 4, 1925) was an American millionaire equestrian and the father of fashion designer Gloria Vanderbilt. He was the founder and president of many equestrian organizations.

Reginald Claypoole Vanderbilt was born on January 15, 1880 on Staten Island, New York. He was the youngest son of Cornelius Vanderbilt II and Alice Claypoole Gwynne. Reginald was a grandson of William Henry Vanderbilt, and great-grandson of Commodore Cornelius Vanderbilt.

He attended Yale University, but did not graduate. His elder brother Cornelius Vanderbilt III married Grace Wilson against his parents wishes, and the second son, Alfred, died when the RMS Lusitania sank on May 7, 1915, so Reginald was left as his parents' logical successor.

In 1903, he married Cathleen Neilson. The couple had a daughter, Cathleen Vanderbilt, and were divorced in 1920.

He remarried on March 6, 1923, to Gloria Morgan with whom he had a second daughter, fashion designer Gloria Laura Vanderbilt. Reginald is the maternal grandfather of CNN television news anchor Anderson Hays Cooper and his late brother, Carter Vanderbilt Cooper, through daughter Gloria.

He died from cirrhosis due to alcoholism on September 4, 1925 at his country home, Sandy Point Farm, in Portsmouth, Rhode Island.
