Ventura was born James George Janos on July 15, 1951 in Minneapolis, Minnesota, the son of George William Janos and his wife, Bernice Martha (nee Lenz). Both of his parents were World War II veterans. Ventura has an older brother who served in the Vietnam War. Ventura has described himself as Slovak, since his father's parents were from what is now Slovakia; his mother was of German descent.

After the legislature refused to increase spending for security, Ventura attracted criticism when he decided not to live in the governor's mansion during his tenure, choosing instead to shut it down and stay at his home in Maple Grove. Critics pointed to the loss of jobs for several working-class people at the mansion and the extra cost of reopening the mansion later.  In 1999, a group of disgruntled citizens petitioned to recall Governor Ventura, alleging, among other things, that "the use of state security personnel to protect the governor on a book promotion tour constituted illegal use of state property for personal gain." The petition was denied. The proposed petition was dismissed by order of the Chief Justice of the Supreme Court of Minnesota. Under Minnesota law, a proposed petition for recall is required to be reviewed by the Chief Justice for legal sufficiency, and, upon such review, the Chief Justice determined that it did not allege the commission of any act that violated Minnesota law. Ventura sought attorney's fees as a sanction for the filing of a frivolous petition for recall, but that request was denied, on the ground that there was no statutory authority for such an award.  In November 2011, Ventura held a press conference in relation to a lawsuit he had filed against the Transportation Security Administration. During that press conference, Ventura stated that he would "never stand for a national anthem again, I will turn my back and raise a fist the same way Tommy Smith and John Carlos did in the '68 Olympics, Jesse Ventura will do that today."  During his tenure as governor, Ventura drew frequent fire from the press in the Twin Cities. He referred to reporters as "media jackals," a term that even appeared on the press passes required to enter the governor's press area. Shortly after Ventura's election as governor, author and humorist Garrison Keillor wrote a satirical book about the event, spoofing Ventura as "Jimmy (Big Boy) Valente," a self-aggrandizing former "Navy W.A.L.R.U.S. (Water Air Land Rising Up Suddenly)" turned professional wrestler turned politician. Initially, Ventura responded angrily to the satire, but later, in a conciliatory vein, said that Keillor "makes Minnesota proud". During his term, Ventura appeared on the Late Show with David Letterman, in which he responded controversially to the following question: "So which is the better city of the Twin Cities, Minneapolis or St. Paul?". Ventura responded, "Minneapolis. Those streets in St. Paul must have been designed by drunken Irishmen". He later apologized for the remark, adding that it was not intended to be taken seriously.
