Jones had a heart attack in his home on Sunday in Washington, Virginia, as he was waiting to watch his beloved Atlanta Braves play baseball, his wife said on social media.
Rappahannock County Sheriff Connie Compton confirmed his death.
Jones' fame came from his role as Cooter Davenport, the mechanic who got the Duke boys out of jams as they tried to do the right thing and fight the corrupt Boss Hogg in the fictional Hazzard County, Georgia.
After playing Cooter for all seven seasons of the series from 1979 to 1985, Jones turned to politics and was elected to the US House from a district near Atlanta in 1988. The Democrat served two terms before he was redistricted out of the seat.
Jones was born in North Carolina and in college got involved in acting and civil rights, he wrote in his autobiography Redneck Boy in the Promised Land: The Confessions of Crazy Cooter.
Jones performed in numerous stage productions and had a few minor TV and movie roles in Atlanta during the 1970s before his life-defining break came on a TV show Jones defended as a modern-day morality tale and a fine example of Southern values.
For seven seasons, Jones was one of a small band of friends and family helping Bo and Luke Duke in The Dukes of Hazzard. The brothers were on probation for running moonshine and were constantly trying to clear their names and stop the crooked and powerful Boss Hogg from stealing or cheating.
The Duke boys drove a modified 1969 Dodge Charger called the General Lee with a Confederate flag on its roof. Cooter owned Cooter's Garage in the town square. Nearly every episode involved a car chase with jumps and stunts and a patrol car badly in need of repairs.
The Dukes of Hazzard was a hit for CBS and its popularity never waned.
Jones also credited the series with pulling him out of a self-destructive, alcoholic lifestyle that led to the failure of several marriages.
"It was like being in a Beatles movie," Jones said. "Our lives changed."
After The Dukes of Hazzard, Jones went into politics. He kept his aw shucks personality, but took the issues seriously. In his four years in Washington, Jones was known as a Democrat who could buck his party. He was liberal on social issues and conservative on economics.
But even in politics, he made a splash. After losing in 1992 in his redrawn district, Jones ran for Congress again in 1994. He lost to Newt Gingrich in the elections that elevated the Republican to the Speaker's Office.
Jones would file an ethics complaint that Gingrich used tax-deductible donations to fund his partisan college course leading to a House reprimand and Gingrich's decision to leave the body.
