Nathan Lewis Miller (October 10, 1868 – June 26, 1953) was an American lawyer and politician who was the 43rd governor of New York from 1921 to 1922.

The merger helped Carnegie get out of the steel business and make him one of the richest men in the world at the time.

On January 13, 1913, he was designated an associate judge of the New York Court of Appeals under the amendment of 1899, but resigned from the bench on July 30, 1915.

Miller was a strong supporter of the Roman Catholic Church, his wife's religion, and converted to Catholicism on his deathbed.

He and his old adversary Smith was active in the American Liberty League, a bipartisan anti-New Deal group founded by wealthy conservatives.

In January 1952, the New York State Bar Association awarded Miller its first gold medal for "distinguished service to the legal profession."
