I'm a US citizen, can I marry my girlfriend who's illogal in the Bahamas?

You may be able to file a fiancé visa, or you can marry her and petition for her here and wait until she goes through consular processing before you can bring her back to the US. Good luck.
The Bahamas is not part of the US. It appears from your question that you can sponsor her. More facts are needed to asses the case. Discuss with counsel here in Florida.
I am not your attorney and don't know anything about your problem. Do not rely on my response other than as information used to hire an actual attorney.
