John J. McDade (June 27, 1856 – November 8, 1937) was an American patternmaker, educator, lawyer and politician who served in the California State Assembly from 1880 to 1881, as chief deputy superintendent of streets of San Francisco from 1883 to 1886, and as sheriff of San Francisco from 1893 to 1895. He also served as the first grand president of the Young Men's Institute.

During his tenure as sheriff, McDade was noted for appointing a woman, May Simpson, as a deputy. He was nominated for the State Board of Equalization in 1902, but withdrew just days later after his physician advised him that he was not healthy enough to campaign.
