The Toodyay Post Office and residence is located in Toodyay, Western Australia on the corner of Stirling Terrace and Duke Street North. It was designed by colonial architect George Temple-Poole and was part of a scheme by the Public Works Department. Over 100 post offices were built to a standard design during the late 1890s; the Toodyay Post Office is one of the few remaining examples. Postal services began in Toodyay in 1842. Some weather measurements were taken at the post office in Toodyay in the 1940s.
