The answer depends on where you are coming from. If you are a United States citizen, located in the US, and will not be transiting through a foreign country (an example is driving from Alaska, through Canada, to the lower 48 states) then you will not need a passport. In the Alaska example, flying from Alaska direct to a point in the "lower 48" will not require a passport. If you are a citizen of another country, the answer is likely "yes", and could require you to have an American visa if your stay is over 90 days in country.
