Julia C. Addington (June 13, 1829 – September 21, 1875) was an American elected official in Iowa.

She had been acting school superintendent just prior to the election, completing the term of the previous holder of that position.

Addington was elected as part of the "Bolter" faction of the Republican Party, who favoured Mitchell as the county seat.

She received exactly the same number of votes as Republican candidate Milton N. Browne and the election was settled by flipping a coin.

Because she was a woman, her election was not universally accepted, even though the Iowa attorney general Henry O'Connor ruled that her election was legal since there was no explicit requirement in the law for a candidate to be male.
