Sunny Corner is a small village in the central west of New South Wales, Australia and former mining area located between Lithgow and Bathurst just north of the Great Western Highway (Route 32). At the 2006 census, Sunny Corner had a population of 626 people.
Sunny corner was never officially known as Sunny Corner until it was gazetted in 1885. In consequence the place was brought into existence by the development and success of the Sunny Corner Silver-mining Company's mine, and therefore the people generally acquired the habit of calling the whole place, including the newly surveyed town, after the company's property. By November 1884 there was talk of Sunny Corner being named Mitchell. This became a reality by February 1885, however the townsfolk were not in favour of the new name. The township was also called Mitchell's Creek but the local community always called the area Sunny Corner and the name continued in use.
