Nicholas Theodore Nemeth (born July 27, 1980) is an American professional wrestler. He is signed to Total Nonstop Action Wrestling (TNA), where he performs under his real name (stylized as Nic Nemeth) and is a double champion, being the current TNA World Champion in his second reign and one-half of the TNA World Tag Team Champions with his brother Ryan Nemeth in their second reign. He is best known for his tenure in WWE from 2004 to 2023, where he performed under the ring names Nicky and most notably Dolph Ziggler. After a career in amateur wrestling, where he established several school records for Kent State University, Nemeth signed a developmental contract with WWE in 2004 and was sent to Ohio Valley Wrestling (OVW), where he wrestled under his real name. He was promoted to WWE's Raw brand shortly afterwards in 2005, playing the caddie sidekick to Kerwin White. He was sent back to OVW shortly afterwards, being given the name Nicky and joining the cheerleading-themed Spirit Squad, who debuted on Raw in January 2006 and won the World Tag Team Championship once before returning to development. After working in OVW and Florida Championship Wrestling (FCW), he returned to the main roster, repackaged as Dolph Ziggler, in September 2008. Since then, he held the World Heavyweight Championship twice, the NXT Championship once, the Intercontinental Championship six times, the United States Championship twice, the Raw Tag Team Championship twice, and the SmackDown Tag Team Championship once. His other accomplishments include becoming the sole survivor of two Survivor Series elimination matches and the 2012 Money in the Bank winner as well as headlining multiple WWE pay-per-view events. Nemeth was released from WWE in September 2023, ending his 19-year run with the company. After WWE, Nemeth would debut on the independent circuit using his real name. In January 2024, he made his debut in New Japan Pro-Wrestling (NJPW), appearing in the crowd alongside his brother Ryan at Wrestle Kingdom 18, and made his TNA debut at 2024's Hard To Kill. One month later, he won the IWGP Global Heavyweight Championship, his first major non-WWE championship, in his NJPW debut match. On April 27, at Triplemanía XXXII, he won the vacant AAA Mega Championship. Three months later, on July 20, he would win the TNA World Championship at that year's Slammiversary. In 2025, he won the TNA World Tag Team Championship for the first time with Ryan.
