Aleut Confinement and Relocation Sites Study Act - Directs the Secretary of the Interior to conduct a special resource study to determine whether the following sites are suitable for inclusion in the National Park System: (1) the World War II Aleut relocation sites at Funter Bay, Burnett Inlet, Killisnoo, Ward Lake, and the Wrangell Institute in Alaska; and (2) the villages of Makushin, Kashega, and Biorka around Unalaska Island and Attu on Attu Island in Alaska, from which the Aleut people were forcibly removed.

Requires the Secretary to:

• evaluate the national significance of the sites;
• determine the suitability and feasibility of designating those sites as units of the National Park System;
• consider alternatives for preservation, protection, and interpretation of the land comprising those sites; and
• identify cost estimates for any federal acquisition, development, interpretation, operation, and maintenance associated with carrying out such alternatives.
