The Leader is a weekly newspaper that was first published in Angaston, South Australia on 24 July 1918, and continues being published to the present day in the Barossa Valley. It was the first English-language newspaper covering any part of the Barossa Valley, apart from the Kapunda Herald.^[1]

The Leader was founded and for many years edited and printed by William Kirkby Robinson (1894–1976). Offices were from 1935^[2] or earlier, to December 1938^[3] or later, printing and publishing in Dean Street, Angaston.

From 1933, Robinson was secretary of the Angaston branch of the Agricultural Bureau, and was the founder of the Lower North pruning competition held yearly. He was responsible for the formation of the Barossa Fire Fighting Association in 1926 and has been fire control officer since then, and was for many years chief officer of the Angaston Fire Brigade. He was an unsuccessful candidate for the seat of Barossa at the 1944 House of Assembly by-election.^[4] From 1937 he also published The Sport, an Adelaide weekly. He was for some time chairman of directors of the Provincial Press Co-operative Company Ltd. (an advertising agency linked to the Provincial Press Association of South Australia).^[5] He was married to Agnes Elizabeth Robinson née Knapp; they had one child, (Kirkby) Rae Robinson (1918–1990), who married Molly Mansfield (1918–2003) on 24 January 1942.
