Deirdre Coleman Imus (born 1964) is the founder and president of the Deirdre Imus Environmental Center for Pediatric Oncology, part of Hackensack University Medical Center (HUMC) in New Jersey, United States. She is also a cofounder and codirector of the Imus Cattle Ranch for Kids with Cancer (Imus Ranch), and the author of two books, Greening Your Cleaning and The Imus Ranch: Cooking for Kids and Cowboys.

The Deirdre Imus Environmental Center for Pediatric Oncology conducts research into the possible links between various cancers and environmental hazards. The center received the "Quality New Jersey?s Environmental Award" on May 8, 2006.

On May 7, 2007, she was named to the Board of Directors of the National Autism Association. and on May 22, 2007, the National Audubon Society announced that Deirdre Imus was one of four women to receive the Societys annual Rachel Carson Award for Women in Conservation. In making the announcement, the Audubon Society cited her as, "a pioneer inspiring parents and schools to clean using non-toxic products... convincing more than 200 institutions nationwide to switch to green cleaning products and her work has led directly to three Green Cleaning executive orders that will vastly improve the health of millions of children."

Deirdre Imus has expressed concern over the chemicals used in commercial cleaning products and her book, Greening Your Cleaning, published in April, 2007, advocates the use of alternative cleaning products. Greening Your Cleaning contends that chemicals such as ammonia are harmful and she calls for "environmentally responsible" ways to clean around the house. She appeared on the NBC Today Show (Today (NBC program)) on April 6, 2007, to demonstrate the cleaning methods discussed in her book. A scheduled book tour was postponed, however, in the wake of the controversy surrounding the cancellation of the Imus in the Morning show.

Beginning in the late 1990s, she had some small acting roles as Deirdre Coleman, appearing in Form, Space & Murder in 1997. The following year, she appeared in Watchers Reborn and One Tough Cop, a movie about New York City detective Bo Dietl. In 2001, she had a role in Directing Eddie.

On May 24, 2007, she was awarded an honorary Doctor of Humane Letters degree by Pace University in recognition of her advocacy on behalf of children?s environmental health.
