John J. Dunnigan (September 6, 1883 – December 1965) was an American architect, builder and politician from New York.
In 1919 he introduced a state equal rights amendment for women, who had won the vote in New York two years before.
The bill would have amended the state labor law as follows: “Hereafter in this State every avenue of employment shall be open to women, and any business, vocation, profession and calling followed and pursued by men may be followed and pursued by women, and no person shall be disqualified from engaging in any business, vocation, profession, calling or employment on account of sex.
He was a delegate to the New York Convention to ratify the Twenty-first Amendment to the United States Constitution in 1933.
His son James J. Dunnigan (1912–1983) was President of the Buffalo Raceway in Hamburg, NY from its establishment in 1942 until the 1960s.
