John McKail (22 January 1810 – 6 August 1871) was an early settler of Western Australia. He was among the first arrivals in the Swan River Colony in 1829, but in 1835 was banished to Albany after trouble with the law. In Albany, he set up as a merchant and subsequently developed interests in a number of fields. He owned hotels, invested in whaling, and exported sandalwood to Asia. McKail served in the Legislative Council from 1870 to 1871, as one of the council's first elected members.
