Narellan Vale is a suburb of Sydney, in the Australian state of New South Wales. Narellan Vale is located 60 kilometres south-west of the Sydney central business district, in the local government area of Camden Council and is part of the Macarthur region.

The area now known as Narellan Vale was probably originally home to the Tharawal people, based in the Illawarra region, although the Western Sydney-based Darug people and the Southern Highlands-based Gandangara people were also known to have inhabited the greater Camden area. Very early relations with British settlers were cordial but as farmers started clearing and fencing the land affecting food resources in the area, clashes between the groups arose until 1816 when a number of indigenous people were massacred and the remainder retreated from direct conflict with the settlers.

In 1805, wool pioneer John Macarthur was granted 5,000 acres (20 km) at Cowpastures (now Camden). After the land was cleared, it was used for farming until the mid-1980s when Sydney's suburban sprawl reached the town of Camden and Areas like Narellan Vale were Established.

In 1986 Narellan Vale was established and then two years later in 1988 Elizabeth Macarthur High school opened and then a few years later Narellan Vale Public School And St Clare's Catholic Primary School opened, the suburb was completed by 1998.
