Vincent Samson Appice (/ˈæpəsiː/ APP-ə-see, born September 13, 1957) is an American rock and metal drummer best known for his work with the bands Dio, Black Sabbath, and Heaven & Hell. He is the younger brother of drummer Carmine Appice.

Appice took up the drums at the age of nine, taking lessons from the same teacher as his brother Carmine Appice. When he was sixteen, Appice and his band BOMF met John Lennon at Record Plant Studios. Lennon took a liking to the group and used them as a backing band in several performances, including the final one before his death. Appice moved on to record with Rick Derringer on Derringer (1976), Sweet Evil (1977), and Derringer Live (1977), before forming his own band Axis and recording It's A Circus World (1978).

Appice joined Black Sabbath during the tour in support of the band's Heaven and Hell album in 1980. Sharon Arden had approached him with an offer to join Ozzy Osbourne's new band but he turned it down at the urging of his older brother Carmine. About a month later he was approached by Black Sabbath, whose longtime drummer Bill Ward had just departed mid-tour to deal with personal issues. Appice was told over the phone that Ward was "missing in action", and he subsequently met with Tony Iommi and the pair hit it off. Iommi was a fan of Appice's work on Axis' It's A Circus World and he invited Appice to meet the rest of the band and rehearse in Los Angeles the following day. When he initially joined Black Sabbath, he was expected to only complete the tour, as it was anticipated that Ward would return at some point.

Appice's first show with Black Sabbath was at the Aloha Stadium in Hawaii. Though he had rehearsed the songs in Los Angeles before leaving for Hawaii, he was forced to use hastily written crib notes on stage for each unfamiliar song. "The endings were a bit sloppy and long, but as the tour went on it got tighter and tighter," Appice recalled of his early days in the band. After several months it became apparent that Ward would not be returning, and Appice became the band's permanent drummer. He subsequently appeared on the 1981 Black Sabbath studio album Mob Rules and the 1982 live album Live Evil.

In late 1982, vocalist Ronnie James Dio left Black Sabbath and asked Appice if he would be interested in forming a new band with him. Though Appice was still a member of Black Sabbath, he and Dio lived in the same town in New York and the two had a close relationship. As Sabbath were based in England, Appice thought it would be more convenient to stay in the United States and work with Dio, and the band Dio was soon formed along with Vivian Campbell and Jimmy Bain. He recorded the albums Holy Diver (1983), The Last in Line (1984), Sacred Heart (1985), Intermission (1986), and Dream Evil (1987) with the band. In December 1989, Appice left Dio and briefly teamed up with ex-Dokken bassist Jeff Pilson in the short-lived band Flesh & Blood.

Ronnie James Dio rejoined Black Sabbath in 1992 to record the album Dehumanizer. The band were working with drummer Cozy Powell, but Powell was unable to record after falling off a horse and breaking his pelvis. They immediately called Appice, who flew to Wales to rehearse and record with the band. "I like Vinny, he's a nice chap," Tony Iommi said of the reunion. "Vinny was asked to continue with the Sabbath thing (in 1982), but he didn't. I like Vinny's playing."

Appice rejoined Dio and they recorded Strange Highways (1994) and Angry Machines (1996). Prior to the 1996 tour, Appice played drums for Las Vegas–based guitarist, Raven Storm, on his album The Storm Project, which also involved long-time Dio engineer and producer, Angelo Arcuri. Arcuri was also a childhood friend of the Appice brothers.

In 2005 Appice appeared on a rap recording by Circle of Tyrants, whose lineup included Necro, Ill Bill, Goretex, and Mr Hyde, also collaborating with Alex Skolnick. Appice played two shows in Las Vegas with the Sin City Sinners in October 2009. Appice rejoined his Black Sabbath bandmates Ronnie James Dio, Geezer Butler, and Tony Iommi in 2006 as Heaven & Hell, touring and releasing one studio album, The Devil You Know, before Dio's death in 2010.
