Justine Polier (née Wise; April 12, 1903 – July 31, 1987) was an American lawyer, the first woman Justice in New York.

[4] As a young woman, she studied labor relations and advocated for workers’ rights, while also working at Elizabeth Peabody Settlement house and a textile mill.

[7] Preferring social legislation to practicing law, Polier worked as the first woman referee and in 1934 Assistant Corporate Council for the Workman's Compensation Division.

[4] In 1935, New York City Mayor Fiorello H. La Guardia made Polier a judge on the Domestic Relations Court.

[4][6] In her time serving as judge, Polier was deeply involved in combating de facto segregation in the New York school system and institutional racism elsewhere in the public sector.

[4][8] She, along with Justice Jane Bolin, also fought racial discrimination by religious groups by helping to found a special school for black boys in New York.

[7] In 1942, she and Justice Jane Bolin helped pass a "Race Discrimination Amendment" penned by her husband in the New York City's appropriations budget.

[7] During what she called her "second day," Polier worked to broaden services to troubled children and their families with organizations like the Citizens' Committee for Children, the Field Foundation, and the adoption agency founded by her mother in 1916[7] and renamed "Louise Wise Services" by Polier, who served as president of its board of directors beginning in 1946,[6] and the Wiltwyck School.
