Winthrop Paul Rockefeller (September 17, 1948 – July 16, 2006) was a Republican politician who served as the 13th Lieutenant Governor of the US state of Arkansas from 1996 until his death.

Winthrop Paul Rockefeller was born New York, and was the only child of Mr. Winthrop Rockefeller, the former Governor of Arkansas, and Mrs. Barbara Sears Rockefeller, and was known to his family and friends alike, as "Win".
His parents separated in 1950 and divorced four years later.
Rockefeller grew up in both the United States and in Europe and was educated at schools in New York, England and in Switzerland. He graduated from Texas Christian University (TCU) with a degree in Ranch Management.

Rockefeller served from 1981 to 1995 on the Arkansas State Police Commission. In 1991, he was appointed by PresidentGeorge H. W. Bush to serve on the President’s Council on Rural America and was elected chairman. Rockefeller also was a president of the Quapaw Area Council of the Boy Scouts of America and served on the Boy Scouts National Board of Directors.
He was elected lieutenant governor in a November 1996 special election triggered by the resignation of Governor Jim Guy Tucker and the promotion of then-Lieutenant Governor Mike Huckabee. Rockefeller was subsequently re-elected in 1998 to a full four-year term, receiving 67 percent of the vote. Rockefeller was elected once again in 2002 with 60 percent of the vote.
According to his website: "As lieutenant governor he focused on economic development, education and literacy. As acting governor on September 11, 2001, the day terrorists attacked the World Trade Center and the Pentagon, he resisted calls to declare a state of emergency and instead urged Arkansans to remain calm and to donate blood, which they did. He sponsored Project ChildSafe, a national firearms safety program that has distributed hundreds of thousands of free trigger locks in Arkansas, and he served as honorary chairman of the Arkansas Literary Festival. In 1997, Rockefeller created Books in the Attic, a program using existing resources, Boy Scouts, and volunteers to ensure access to reading opportunities for all children. In 2004, he served as chairman of the Republican Party of Arkansas."^[1]
