The new school in Farmland Drive at Schofields will be named in honour of the area's Aboriginal custodians.
Currently under construction, the school, which is located on Darug land, will be known as Galungara Public School.
Riverstone MP Kevin Conolly said the word Galungara was Darug for "the stem" or "flower stalk" of the Xanthorrheoa Australis (grass tree).
The tree itself is an ancient species which grows in south-eastern Australia and produces a resin that has been used by aboriginal people for thousands of years to make traditional tools and adornmments.
"Naming the school 'Galungara' provides the opportunity to acknowledge our Darug predecessors," Mr Conolly said.
"I am advised that the whole school project will continue the sense of connection with the Aboriginal custodians of the land through the choice of the school name, emblem, building identifiers, playground space and uniform."
Education Minister Sarah Mitchell said the name was chosen after community consultation, via an online platform where four possible names were proposed.
"Support for the name 'Galungara' was strong with 48 per cent of the incoming parent community, Department of Education personnel and the wider local community voting for this name," she said.
"Darug Ngurra, formerly The Aboriginal Tribal Corporation, along with Nurragingy Aboriginal Education Consultative Group (AECG) also expressed their support of Galungara in recognition of its significance to the Darug people."
The new school will cater to the rapidly growing population in the Schofields area.
Blacktown Council reports that in 2020 the population for the Alex Avenue precinct land release, where the school is situated, will be 9,551 and is forecast to grow to 19,174 by 2036.
Galungara Public School will cater for up to 500 students from Kindergarten to Year 6 but it has been master planned for up to 1,000 students.
The school will be operational from day one, term one 2021.
