Chislehurst was a former house and former school building located in Chatswood West, Sydney, New South Wales, Australia.

Completed in 1892 by the merchant and pastoralist John de Villiers Lamb, the former house was originally known as Maroomba.

It was renamed Chiselhurst after the birthplace of Carr Hordern's wife, Lillie.

His widow and sister continued to live there until the house was vacated in 1954.

The property was then acquired by the NSW Department of Education as a site for Chatswood High School, which opened in 1959.
