Cruises that begin and end at the same port in the United States are considered closed-loop. The cruise must also include a visit to at least one foreign port in the Western Hemisphere. For example, a cruise that sails from Port Canaveral, visits the southern Caribbean and returns to Port Canaveral is considered a closed-loop cruise. A repositioning or Panama Canal cruise is not closed-loop because the cruise begins and ends in different cities.
On most cruises yes. But not on "Closed Loop cruises" see http://getyouhome.gov for all the passport rules!

closed loop system
In a closed loop system the gain without the feed back loop being closed is called open loop gain!!! e.g if forward gain is "A" and feed back factor is "B" then open loop gain is "AB" and closed loop gain will be [A/(A+B)]
All cruise lines strongly recommend you get a passport, but it's not required for "closed loop" cruises in the Western Hemisphere. http://www.cruisesavvy.com/savvyguide/know_before_you_go/do_i_need_a_passport
