Anthony D. "Tony" DiNozzo Jr./dɪˈnoʊzoʊ/ is a fictional character in the CBS TV series NCIS portrayed by American actor Michael Weatherly. An original character created by producer Donald P. Bellisario, he is credited in 306 episodes of the series, appearing in 305. He has also made guest appearances on the spin-offs NCIS: Los Angeles and NCIS: New Orleans.

Tony is scripted as the senior field agent of the fictional Major Case Response Team (MCRT) led by Gibbs. A former police detective, he is athletic and charismatic—at least, when not being snarky/smarmy—he describes himself as a former jock, and often leads crime scene investigations; when not at work he is a movie buff. Over the course of the show, he carries a few storylines, namely an undercover assignment that carries through Season 4 and into Season 5. In general overview, he is renowned for providing comic relief for an otherwise serious drama show, regularly spouting movie trivia, and, especially in the early seasons, being a womanizer who fears commitment. The death of Sasha Alexander's character, Ex-Secret Service Agent turned NCIS agent Caitlin Todd, in the second season finale and his relationship with Cote de Pablo's character, Mossad officer turned NCIS agent Ziva David, who is introduced in the third season, becomes fundamental to his subtle shift in attitude.

The character drew mixed reactions from the audience. According to Bellisario, Tony was often criticized by the female audience at the beginning of the show's run for his chauvinism. This softened after Weatherly decided to tone down that aspect of his portrayal, and afterwards the character was better received. Critics continued to be both amused and annoyed by his "charming goofball" persona, and his "will they/won't they" relationship with Ziva later became popular among viewers. By 2011, Weatherly was listed among the top 10 most popular actors on primetime television, according to Q Score.
