Meek Mill wanted to enter the Cosmopolitan Hotel and Casino in Las Vegas to see a DJ Mustard show this afternoon.

He was dramatically denied entry and threatened with arrest if he continued to try.

Meek said he had only been the hotel one other time five years ago, and he has no idea why he would be on a banned list.

His lawyer Joe Tacopina told TMZ he believes the ejection was racially motivated.

Meek's lawyer, Joe Tacopina, tells TMZ, the head of security made it clear -- the decision to ban Meek came from above ... the security chief said, "This comes from way higher up than me."

Tacopina says he spoke with someone whom he says is "a well-placed person inside the hotel" ... whom Tacopina says told him a group of hotels have tried to keep rappers out of the hotels. Tacopina claims it's racially motivated, saying, "They wouldn't ban Vanilla Ice."

Meek also believes race played a role in what went down.

If you come from our culture you should never step foot in the cosmopolitan hotel they just really racist as hell .... something really has to be done in Las Vegas what they doing to black people!
