Terry Funk (born 30 June, 1944) is an American professional wrestler known by some modern fans for his excessively violent, hardcore matches. His style of wrestling inspired many later wrestlers, most notably Mick Foley, and Terry Funk is one of the greatest journeyman wrestlers in the television era. He is affectionately known as "The Funker."

Funk started out his career in his father (Dory Funk, Sr. )'s promotion in Amarillo, Texas. He and his brother Dory Funk, Jr. quickly rose the ranks and became big money wrestlers by the end of the decade. In his tenth year as a pro, Terry defeated Jack Brisco for the National Wrestling Alliance's NWA World Heavyweight Championship, then the most important wrestling championship in the business, and began a grueling fourteen-month title reign which ended in Toronto when he was defeated by "Handsome" Harley Race who won the title for the second time. Terry Funk took some time off after his world title reign but he and his brother traveled around the country (mostly in Texas, Florida and Detroit) looking for a fight. Terry and Dory, Jr. also made a name for themselves in Japan where they became one of the top drawing foreign acts in the history of Japan. He made a name for himself with his over the top mannerisms and sometimes colorful get-ups as well as his brawling ability.

In in the mid 1980s, Funk teamed with his brother Dory and Jimmy Jack Funk. They were managed by Jimmy Hart. Eventually the brothers dumped Jimmy and brought in Mother Funker (Ms. Elizabeth).

In 1994 Funk promised to help the fledgling ECW (Eastern and later Extreme Championship Wrestling) by lending his talent and notoriety to the promotion, which had just split from the NWA. Funk maintained a regluar schedule of wrestling for ECW in its early days while also competing in Japan and had many feuds and programs with wrestlers such as Mick Foley (as Cactus Jack), "The Franchise" Shane Douglas, the Sandman, Sabu and Terry's own protege, Tommy Dreamer.

Terry Funk further elevated ECW by headlining their first Pay-Per-View, Barely Legal, on April 13, 1997 and winning the world heavyweight title from Raven (Scott Levvy). He was later defeated for the title by Sabu (Terry Brunk) in a much talked about barbed-wire match, in which the ropes of the ring were taken down and replaced with barbed-wire.

Chainsaw Charlie was the name used by Terry Funk in WWE for a short period in 1998. As Chainsaw Charlie, Funk won the WWE's World Tag Team Championship with Mick Foley (using the name Cactus Jack) at WrestleMania XIV, when they beat the New Age Outlaws in a Dumpster Match.

In 1999 Funk was featured in director Barry Blaustein's wrestling documentary, Beyond the Mat. He has also appeared in notable movies Roadhouse, Over the Top, and Texas Chainsaw Massacre as well as other film credits. His legendary toughness was attested to in the wrestling documentary when cameramen followed him to a doctor's visit where he was told he shouldn't even be able to walk without intense pain.

Currently Funk is semi-retired (although he has claimed to be retired many times, he always seems to come back, which has become a recurring joke among wrestling fans) working some dates with independent promotions and in Japan.
