Luar do Sertão (Hinterlands Moonlight in English) is a popular Brazilian song. Its verses are simple and naive praising the life in sertão. Sertão is a Portuguese word for hinterlands, countryside or outback. It was originally a coco under the title "Engenho de Humaitá" (Humaitá's mill). Catulo da Paixão Cearense argued to be the unique composer of the song, however, nowadays the credit is given to João Pernambuco (1883-1947). It is one of the most recorded Brazilian songs of all time.
