Parramatta, pronounced /ˌpærəˈmætə/ and traditionally known by the Dharuk name Burramatta, is a prominent suburb and commercial center situated in Greater Western Sydney. Positioned about 24 kilometers west of Sydney’s Central Business District (CBD), it occupies a key location on the banks of the Parramatta River. With a population of 30,211 recorded in the 2021 Census, it is one of the most densely populated suburbs in the region, with approximately 5,700 residents per square kilometer.

Established in 1788, the same year as the founding of Sydney, Parramatta holds historical significance as one of Australia's earliest European settlements. It has since evolved into a vital economic, cultural, and administrative center. Known as Sydney’s “second CBD,” Parramatta plays a critical role in the metropolitan structure of New South Wales. It falls under the governance of the City of Parramatta Council and is part of the Greater Western Sydney metropolitan area.

The suburb spans an area of 5.3 square kilometers and is bordered by other key localities such as North Parramatta, Westmead, and Harris Park. It is situated at an elevation of 18 meters and is represented in both state and federal electorates including Parramatta, Baulkham Hills, and Granville.

Modern-day Parramatta is known for its mix of high-rise developments, historical landmarks, retail hubs, and a diverse cultural scene. Its continued growth and strategic position make it a major focus for infrastructure investment and urban renewal projects, reinforcing its status as a vibrant urban core outside of the traditional Sydney CBD.
