Baron Paul Hill (born June 23, 1953) is a retired American politician who served as a U.S. Representative for Indiana's 9th congressional district from 1999 to 2005 and from 2007 to 2011.

A native of Seymour, Indiana, Hill is a Democrat, and as a member of Congress belonged to the conservative-leaning Blue Dog Coalition of that party.

Hill's district is in the southeastern part of the state, stretching from Bloomington to the Indiana side of the Louisville metropolitan area.

Hill attracted much attention (and earned media) during that race for walking the length of the state (from the Ohio River to Lake Michigan) to meet with voters.

[5][7] Hill ultimately lost to Senator Dan Coats (who the governor had appointed to fill the vacancy), 54% to 46%—a smaller margin than expected.

[7] During five non-consecutive terms in the United States House of Representatives, Hill was a member of the Blue Dog Coalition of moderate and conservative Democrats.

[15][16] In October 2003, Hill said that the 2003 invasion had been well-planned but the subsequent reconstruction had not: "The president did not plan well for winning the peace and for rebuilding the nation.

[7] Hill voted against the Emergency Economic Stabilization Act of 2008, which created the Troubled Asset Relief Program ("Wall Street bailout").

[7] Hill supported the American Clean Energy and Security Act of 2009 (Waxman-Markey), a cap-and-trade bill which ultimately did not pass.

He defeated Republican Jean Leising, 51% to 48% and Libertarian Diane Merriam, 1%, winning the seat vacated by retiring 34-year incumbent Lee H. Hamilton.

[30] Texas millionaire Bob J. Perry gave more than $5 million to the Economic Freedom Fund, a 527 group, which included Hill as one of its targets.

In 2011, after leaving Congress, Hill was hired by APCO Worldwide, "as a senior vice president in the company's government relations practice and a member of the firm's international advisory council.

[45] In 2014, Hill left APCO to start his own solo lobbying firm, representing Cook Industries, a company located in his former district.

[48] Former Governor Evan Bayh, who from 1999 to 2011 served in the Senate in the same seat held by Coats, initially opted against joining the race.
