Rapper Juvenile just pled "not guilty" to disorderly conduct after his arrest last month, following a brawl at a Miami hotel ... TMZ has learned.

As we reported, Juvenile -- real name Terius Gray -- was arrested for his alleged involvement in a fight that began inside LIV nightclub and spilled outside to the front of the hotel.

Security told police the people involved in the fight were "creating a threat to life and property as well as the overall safety of the patrons inside."

Juve had just reunited with Lil Wayne at the time -- following a long-standing feud -- but the rapper insisted Weezy was not involved.
