John Patrick O’Brien (February 1, 1873 – September 22, 1951) was an Irish-American attorney and Democratic politician who served as the 99th Mayor of New York City from January 1 to December 31, 1933. Born in Worcester, Massachusetts, to Irish immigrant parents, he earned degrees from the College of the Holy Cross and Georgetown University before moving into municipal law and judicial service in New York. Backed by the Tammany Hall political machine, he won a special election following the resignation of Jimmy Walker and served a single year in office, during which he worked to stabilize the city’s finances amidst the Great Depression. He was defeated for re-election and returned to private practice.
