Is this sentence correct?
I don't have nothing.
You're right FiveJJ and excuse me for putting in my two cents' worth. Maybe it's useful to point out that such double negatives, although technically incorrect, are very common in conversation in certain contexts, especially in US English. And that they wouldn't necessarily be seen as wrong or unusual by others in that context. For example:
"You won't have nothin' left".
"I ain't got nothin' to lose".
"I ain't got no chance of winning".
Such phrases have a flavour and effectiveness of their own.
There are plenty of parts of the UK where you can hear sentences like that too.
