Christine Haider (1947–2023) was a dedicated leader in her Flushing community. She served on Queens Community Board 11 for more than 30 years and was the first female Board Chair from 2014 to 2019, leading an all-female group of officers. Her deep knowledge of board rules and procedures earned her the nickname "the parliamentarian" of the community board. She also presided over the Harding Heights Civic Association and was an active member of numerous local, national, and international organizations, including the Saul Weprin Democratic Club, the National Notary Association, and the International Association of Administrative Professionals. Haider was deeply engaged in various local issues, such as infrastructure improvements, zoning protections, and school safety.

Haider also had a long career in administration. She worked as an executive secretary for the National Industrial Conference Board in New York City and for Columbia University before becoming an administrator in Columbia’s Partnership for Gender-Specific Medicine in 1978. From 2005 to 2007, she worked as a human resources specialist, assisting the medical recruiter for the New York Army National Guard.

Haider was married to her husband, Howard (1941–2016), for 49 years. He also has a street named in his honor, located at the corner of 207th Street and Northern Boulevard.
