Edward Swann (March 10, 1862 – September 19, 1945) was an American lawyer, jurist, and politician from New York. From November 4, 1902, to March 3, 1903, he served part of one term in the U.S. House of Representatives.
Afterwards he resumed the practice of law in New York City. In November 1904, Swann ran again for Congress, this time in the 13th District, but was defeated by Republican Herbert Parsons.
In November 1907, Swann was elected a judge of the Court of General Sessions, and took office on January 1, 1908. He was New York County District Attorney from 1916 to 1921, elected in a special election in November 1915 defeating the incumbent Charles A. Perkins, and re-elected in November 1917 to a full term. Swann was accused several times by reform organizations of misconduct and malfeasance in office, urging his removal. Since the precedent of 1900, when Asa Bird Gardiner was removed by Gov. Theodore Roosevelt, this had become a constant move in New York City politics, but neither Republican Charles S. Whitman nor Democrat Al Smith saw reason enough to act.
In November 1920, Swann ran for the New York Supreme Court (1st D.), nominated by the Tammany bosses to get rid of him in the D.A.'s office. After his defeat, Tammany insisted in trying to get him appointed to a vacancy in the New York Court of General Sessions, but Governor Al Smith did not yield. However, for most of the year 1921, Swann remained out-of-state, partly in Florida, partly in Missouri, and left the office in the hands of his chief assistant district attorney, Joab H. Banton.
