Necessary, no, advisable, yes. Currently the only Country that says a passport is required is Belize in Central America but even they may have special rules for cruisers. I have heard rumors for quite awhile now that sometime in the future some of the islands may require a passport but like I said, that rumor has been floating around for quite some time. In any case, if you have the time then getting a passport is just the best idea. They only cost $60 and are good for 10 years and are recognized as legal ID anywhere in the world. You never know, even on a ship, when you may have to get off and fly home or something and then a passport makes sure you have no problerms at all. Go to the links section on the homepage and check out the info on the state department site.

I have to agree with Robo, a picture drivers license and an origional birth cirtificate will do, but its just so much easier cruising with a passport. If you plan on more cruises or vacations, I'd suggest picking up a passport and they are good for 10 years.
Here is a link with information on optaining a passport:
A passport is a great thing to have when returning to the US and clearing Immigration. I have never had any trouble with Customs or Immigration since I have had my passport. I have seen folks without a passport standing in long lines while I 'sailed' on through.
Even when returning from a land vacation to, say Cancun, the passport does ease the homecoming.
As Pam said, another opportunity to look goofy!! Actually Passports serve another purpose when you are not travelling....just hang it in the basement to keep the mice away!!!
