Chidlow is a small community in the Shire of Mundaring approximately 45 kilometres east of Perth, Western Australia.

Settlement began in 1883 when it became known that Chidlow's Well was to be the terminus of the second section of the Eastern Railway, which was opened in March 1884.

Various proposals have been put forward to rebuild the railway to Midland especially due to the restricted nature of public transport to the Chidlow area.

The Railway Reserve Heritage Trail has become one of the major recreational facilities in the Shire of Mundaring, and is suitable for walking, cycling and horse riding.

Lake Leschenaultia is popular with both locals and visitors and provides safe swimming, canoe hire, walking trails and camping.
