Winthrop Paul "Win" Rockefeller (September 17, 1948 – July 16, 2006) was an American Republican politician and businessman who served as the 17th lieutenant governor of Arkansas from 1996 until his death in 2006.

Rockefeller was elected once again in 2002 with 60 percent of the vote, over Arkansas State Supreme Court Justice Ron Sheffield, the first Black man nominated for statewide office as a Democrat.

[4] As Lieutenant Governor, Rockefeller was an avid proponent of the state’s economic interests, and he often traveled at his own expense to seek out potential foreign investors, while at the same time donating his own governmental salary to charity.

[5] 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.

He sponsored Project ChildSafe, a national firearms safety program that has distributed hundreds of thousands of free trigger locks in Arkansas.

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 October 2005 and March 2006, Rockefeller underwent unsuccessful bone marrow transplants at the Fred Hutchinson Cancer Research Center in Seattle, Washington.

On July 8, 2006, after the failure of his second bone marrow transplant, he returned to Little Rock, where he died eight days later at the University of Arkansas for Medical Sciences.
