Mossgiel is a location in New South Wales, Australia, in Carrathool Shire. It was a township on the coach route between the Lachlan and Darling Rivers (now the Cobb Highway), 50 km southeast of Ivanhoe near the junction with the road to Hillston. The settlement experienced a steady decline during the 20th century. Nowadays Mossgiel township consists of one house (which was once the post office) and a community hall.
Mossgiel was named after Mossgiel farm near Lochlea, in Ayrshire, Scotland, the farm of the poet Robert Burns and his brother Gilbert.
