Wicca is a specific pagan religion. Wiccans belive in two deities, the Horned God and the Goddess. Lark has an amazin forum post about what Wicca is and isn't that I would highly recommend any who is interested in Wicca to read.
Pagan decribes any religion that has multiple deities. All wiccans are pagan. Not all pagans are wiccan.

QuietStar is correct.
Wicca is a very specific religion with very specific beliefs and practices.
The term "Pagan" is an umbrella term that covers a wide variety of religions of which Wicca is only one. Although there are some similarities amongst the Pagan religions there are also significant differences as well.
