I got a question for you: An Indian reservation is a legal designation for an area of land managed by a federally recognized Native American tribe under the U.S. Bureau of Indian Affairs rather than the state governments of the United States in which they are physically located. Each of the 326 Indian reservations in the United States is associated with a particular Native American nation. Not all of the country's 567 recognized tribes have a reservation -- some tribes have more than one reservation, while some share reservations. In addition, because of past land allotments, leading to some sales to non-Native Americans, some reservations are severely fragmented, with each piece of tribal, individual, and privately held land being a separate enclave. This jumble of private and public real estate creates significant administrative, political, and legal difficulties.

Based on this passage, how many indian reservations are in the us?
Let's think first:
The relevant information to answer the above question is: Each of the 326 Indian reservations in the United States is associated with a particular Native American nation.
Therefore, the answer is 326.
