No, due to the fact that Data doesn't experience feelings, he did not have a girlfriend. Although on a couple of occasions he has had encounters with women that were close to romantic, although ended up quite awkward.
Short answer: No
Update:
Data had a sexual encounter with Tasha Yar in the season 1 episode 'The Naked Now', when the crew was infected with an unknown pathogen causing them to, among other things, loose their inhibitions. It was a one time thing that Tasha Yar was embarrassed about.
Data also briefly dated Enterprise crew member Lt. Jenna D'Sora (played by Michele Scarabelli) in the episode 'In Theory'. Data even wrote a special sub-routine just for her.
Depending on what you consider a 'girlfriend', data has had intimate relationships. I would suggest that the brief attempt to date Jenna counts as having at least one girlfriend.
Data did end up with emotions, by means of installing a computer chip.
Lt. Commander Data is the main android character in Star Trek: The Next Generation.
