Adrian George Zmed (born March 14, 1954) is an American actor, singer and television personality, noted for the roles of Johnny Nogerelli in Grease 2 and Officer Vince Romano in the T. J. Hooker television series. His Broadway credits include the starring roles of Danny Zuko in Grease and Marvin in Falsettos.

Zmed was born in Chicago, Illinois, the youngest of three sons of George Zmed, later known as George Zmed-Smith (1916–2010), a Romanian Orthodox priest, who served from 1952 until his retirement in 1983, and his wife, Persida (née Golub) Zmed, later known as Sadie Smith (1923–2015). His father George was a Romanian American born in Chicago to Nicolae and Paraschiva (née Bălan), who had emigrated from Nagykomlós, Temes County, Hungary (now Comloșu Mare, Timiș County, Romania) in the early 20th century. At the age of five, George and his family went to Romania, where he was educated, and returned to the United States in November 1952. His mother Persida was born in Romania. George and Persida were married October 15, 1942, in Timișoara. The couple had three sons, in the following order: Cornel, Walter, and Adrian.

Adrian graduated from Lane Tech High School in Chicago. He began playing football for the school's team until, when playing in 1968, he broke a leg bone which in turn punctured a major artery. He quit sports and began acting, appearing in his high school's production of Guys and Dolls. After being featured on a local TV show as one of Chicago's top high school performers, Zmed transferred to the Goodman School of Drama and began studying voice at the Chicago Conservatory of Music. He graduated with a Bachelor of Fine Arts from the Goodman School of Drama.

Zmed's first major acting gig was the role of Johnny in the national touring company production of Grease. He later appeared in the Broadway musical three times, twice in the role of Danny. At 40, Zmed revived the role of Danny in the 1995 Broadway revival.^{[citation needed]}

In 1978, Zmed made his television debut, appearing as Marty Decker in an episode of Starsky & Hutch. From there, he won the role of Socks Palermo in the short-lived television series Flatbush (1979). Following the show's cancellation, he was cast as Frankie Millardo in Goodtime Girls, which lasted one season (1980). He had guest roles on such series as Angie, I'm a Big Girl Now and Bosom Buddies, and made a guest appearance on An Evening at the Improv in 1982.

Zmed reached celebrity status as Officer Romano in ABC's T. J. Hooker. He played Fred Feliciano in Victims for Victims: The Theresa Saldana Story (1984) and made guest appearances on a number of television shows throughout the 1980s and 1990s, including Hotel, Empty Nest, Murder, She Wrote and Caroline in the City. After T.J. Hooker was cancelled by ABC in 1985, he was offered the job of host of Dance Fever for its final two seasons, replacing Deney Terrio.  This left him unable to return to T.J. Hooker when it was later picked up by CBS.

He has appeared as himself on VH1's I Love the '80s, Saturday Night Live and The Bozo Show. He appeared as Basil (the "floating head") on the soap opera Passions and participated in VH1's Confessions of a Teen Idol.

Following the huge success of John Travolta and Olivia Newton-John in the movie version of Grease, Paramount Pictures quickly secured the rights to a sequel. Zmed was chosen to play one of the lead roles in Grease 2, Johnny Nogerelli, the new leader of the T-Birds gang. His performance led to other movie roles, including The Final Terror (1983) and Bachelor Party (1984). He appears in the film The Craving Heart (2006).
