Diana Richardson (born January 16, 1983) is an American former progressive Democratic politician who served as a member of the New York Assembly.

[3][4] Richardson was a Brooklyn Community Board 9 member when the Crown Heights Tenant Union, an advocacy organization for tenants that organizes, educations, and helps residents in housing court cases,[6][7] convinced her to run for an open New York Assembly seat on an anti-gentrification platform.

[8] She won the May 2015 special election with just over 50% of the vote,[9] on the progressive Working Families Party (WFP) ballot line, the first to do so in the state legislature.

[4] In 2016, Richardson was arrested for hitting her 12-year-old son with a broomstick, leaving bruises on his arm, and was charged with second-degree assault (a felony), endangering the welfare of a child, criminal possession of a weapon, and menacing.

[22][23] She had reportedly berated and cursed staff, had to be pulled away from a fight with a Crown Heights anti-violence program director before it became violent, set off smoke alarms in her Borough Hall office, refused to use email, and ignored COVID-19 precautions.
