Christel Haeck (born March 9, 1948 in Stuttgart, Germany) is a politician in Ontario, Canada. She was a New Democratic Party member of the Legislative Assembly of Ontario from 1990 to 1995.

Haeck was educated at Trent University in Peterborough and State University of New York at Buffalo in Buffalo, New York. She worked as a librarian at the Fort Erie Public Library from 1974 to 1977, and was head of Special Collections at the St. Catharines Public Library from 1977 to 1990. She is a member of the Ontario Library Association, and has served on the St. Catharines Social Planning Council.

She first ran for the Ontario legislature in the 1987 provincial election, but finished third against Liberal Mike Dietsch in the riding of St. Catharines—Brock . She ran a second time in the 1990 provincial election, and defeated Dietsch by 1,159 votes amid an unexpected NDP majority victory across the province. Haeck served as a parliamentary assistant from 1990 to 1992, and was a member of the NDP caucus executive.

The NDP were defeated in the 1995 provincial election, and Haeck finished third against Progressive Conservative Tom Froese in her bid for re-election. She has not returned to provincial politics since this time.

In 2000, Haeck campaigned to be a part of the six-member St. Catharines delegation to the Niagara Regional Council and finished seventh. She was appointed to the council in 2002, following the death of former mayor Roy Adams . She ran again in the 2003 municipal election, but finished tenth.

Haeck is a board member of AIDS Niagara, and president of Heritage Niagara. In 2003, she supported Susan Howard-Azzeh , a human-rights activist and Palestinian advocate, against what she characterized as unjust accusations of anti-Semitism from the St. Catharines Standard newspaper in 2002. (The Standard had been owned in succession by two companies that were ideologically aligned with a hawkish Israeli position on the Israeli-Palestinian conflict: Conrad Black's Southam Newspapers until 2000, and Izzy Asper's CanWest Global until 2004.)
