North Turramurra is a suburb on the Upper North Shore of Sydney, in the state of New South Wales, Australia. North Turramurra is located 20 kilometres (12 mi) north-west of the Sydney central business district, in the local government area of Ku-ring-gai Council. Turramurra and South Turramurra are separate suburbs.

Turramurra is an Aboriginal word which is thought to mean either big hill, high place, or small watercourse. Early settlers referred to the area as Eastern Road until the name Turramurra was adopted when the railway station was built in 1890. Eastern Road was an area of orchards. Samuel King, born in 1828 in County Donegal Ireland, arrived in Sydney in 1853. With his wife Ann, he established several orchards along Bobbin Head Road and at North Turramurra and was a noted church and community supporter.

Eccleston du Faur secured the name Turramurra. Du Faur was born in England in 1832 and was recognised in Sydney as a supporter of the arts and sciences. He was elected a Fellow of the Royal Geographical Society in 1875 and was an early bush conservationist. Most importantly, Du Faur secured the land for the Ku-ring-gai Chase National Park from the government of the day. The Chase was declared in 1894. Du Faur personally funded and made a road through the bushland to Bobbin Head. In 1895 he built a house on 25 acres (100,000 m) at the Chase Gates. After his death in 1915, part of this property became Lady Davidson Home, a convalescent hospital, later Lady Davidson Hospital.

North Turramurra became a separate suburb from Turramurra when it was officially gazetted as on 5 August 1994.

North Turramurra is home to the sphinx war memorial. This 1.5 m high replica of the Great Sphinx of Egypt was carved out of sandstone in the 1920s by William Shirley, a returned soldier, in memory of fallen comrades.

The suburb is a popular starting point for many bush walkers as it has easy access to Bobbin Head, the upper reaches of Cowan Creek and St Ives Chase.

North Turramurra lies on a narrow spur between two creeks (Lovers Jump Creek and Cowan Creek) that flow eventually to the sea through the Ku-ring-gai Chase National Park on the northern outskirts of the city. The suburb is the northern boundary of the Ku-ring-gai Council. The heavily forested valleys pose a bush-fire threat each summer, but residents are amazed with common sightings of a wide variety of peculiar and beautiful native wildlife around them. You often see wallabies hopping around backyards.
