The star received an Oscar nod in 1959 for The Defiant Ones, in which he starred with Sidney Poitier.
His career spanned six decades and he made more than 120 films including Trapeze, Spartacus and The Vikings.
Clark County coroner Mike Murphy told the Associated Press that the actor died at 2125 local time on Wednesday.Born Bernard Schwartz on 3 June 1925 in New York, the actor served in World War II before taking on the name Tony Curtis when he began his film career in 1949.
He began his career as a heart-throb, but became a respected actor after starring in more substantial roles, starting in 1957 with harrowing showbusiness tale Sweet Smell of Success.
He went on to appear in The Defiant Ones as an escaped racist convict handcuffed to a black escapee.
But he became best known for his role in Billy Wilder's acclaimed comedy Some Like It Hot, where he donned women's clothing.
After his star faded in the late 1960s, Curtis shifted to lesser roles and fell into drug and alcohol addiction.
In the 1970s he turned to television, starring in a number of TV series including The Persuaders! opposite Sir Roger Moore, and Michael Mann's Vegas.
Sir Roger led the tributes to the actor, calling him "a fine actor".
"We had a lot of laughs together for about 15 months, working together every day. He was great fun to work with, a great sense of humour and wonderful ad libs. We had the best of times."
