Christine Callaghan Quinn (born March 25, 1966) is an American politician and executive best known for her tenure as Speaker of the New York City Council from 2006 to 2013. A member of the Democratic Party, she made history as the first openly lesbian and first female to hold the position, serving as the third person in that role overall. Quinn began her political career in the 1990s, working as a staffer for various New York politicians before being elected to the City Council in 1999, representing Manhattan's 3rd district. During her speakership, she focused on issues like affordable housing, same-sex marriage advocacy, and post-9/11 recovery efforts, though her leadership was not without controversy, including criticisms over her close ties to then-Mayor Michael Bloomberg and decisions on development projects like the Hudson Yards redevelopment.

In 2013, Quinn launched a bid to succeed Bloomberg as mayor of New York City but finished third in the Democratic primary behind Bill de Blasio and Bill Thompson. Following her defeat, she transitioned out of elected office and into nonprofit leadership, becoming the CEO of Win (Women In Need), an organization providing services to homeless women and families in New York City, a role she held from 2014 to 2021. Quinn has also served as a political commentator, contributing to networks like CNN and MSNBC. Openly lesbian, she married her partner Kim Catullo in 2012, and they have faced personal challenges including fertility treatments and the loss of pregnancies. Her career reflects a blend of progressive advocacy and pragmatic governance, positioning her as a key figure in New York politics and LGBTQ+ rights.

Quinn's post-political work has emphasized social services and equity, drawing on her legislative experience to address homelessness and women's issues. She has been involved in various boards and initiatives, maintaining influence in New York City's nonprofit and media sectors. Despite her electoral setback, Quinn remains a respected voice in Democratic circles, often consulted on urban policy and gender equality.
