Reddam House Sydney is an independent, co-educational, non-denominational, day school, located in Woollahra (preschool to Year 9) and North Bondi (Years 10 to 12), both Eastern Suburbs of Sydney, New South Wales, Australia.

In 2019 Reddam House was acquired by Inspired Education Group, an international provider of for-profit schools.

The school attracted media attention with reports 36 percent of students, six times the state average, received "special consideration" in the 2006 HSC.

The school grew quickly and a new campus at Woollahra, near Bondi Junction railway station, was opened in 2003.

The Woollahra campus is also home to the Early Learning School, accepting children from one year of age.
