Michael Donald (Mike) Brown (b. August 5, 1952) is a shadow senator from the District of Columbia.

As a shadow senator, Brown receives no pay from the government, receives no budget from the government, and cannot vote on matters before the Senate. While he does not have an office in the United States Senate, the Government of the District provides the position with an office. Brown lobbies the United States Senate and the United States House of Representatives on behalf of the citizens of the District in their attempt to gain full representation in Congress, self-determination, and eventually admittance to the union as a state. As shadow senator, Brown also works with the District's delegate, mayor, and council to advance the interest of local residents on Federal issues. Brown is a member of the Democratic Party.
