Kellyville is a north-western suburb of Sydney, Australia. It is located 26 kilometres north-west of the Sydney central business district, in the local government area of The Hills Shire. Kellyville Ridge and Beaumont Hills are also suburbs in The Hills Shire.

The first people to live in the Kellyville area were the Dharug tribe of Australian Aborigines. They called the area "Bella Bella". The name was later changed to "Kelly's Ville" after James Kelly, an Irish convict who was sent to Australia in 1801. In 1827, Charles Throsby Smith passed through what is now known as Kellyville on his way to search for new grazing land for his cattle station near Liverpool. He named the area "Throsby Vale".

In 1886, a subdivision called "The Hermitage" was created on land owned by Frederick Wright Unwin. This was later renamed "Kellyville Estate". Most of the original houses still stand today and are heritage-listed.

Today, Kellyville is a thriving suburb with a population of over 20,000 people.
