Kenneth Adolf Slessor OBE (27 March 1901 – 30 June 1971) was an Australian poet, journalist and official War Correspondent in World War II. He was one of Australia's leading poets, notable particularly for the absorption of modernist influences into Australian poetry. The Kenneth Slessor Prize for Poetry is named after him.
Slessor was born Kenneth Adolphe Schloesser in Orange, New South Wales. As a boy, he lived in England for a time with his parents  and in Australia visited the mines of rural New South Wales with his father, a Jewish mining engineer whose father and grandfather had been distinguished musicians in Germany (Dutton 1991, 1–2).
His family moved to Sydney in 1903. Slessor attended Mowbray House School (1910–1914) and the Sydney Church of England Grammar School (1915–1918), where he began to write poetry. His first published poem was in 1917 about a digger in Europe, remembering Sydney and its icons. Slessor graduated in 1918 and joined the Sydney Sun as a journalist. In 1919, seven of his poems were published. He married for the first time in 1922.
Slessor made his living as a newspaper journalist, mostly for the Sydney Sun, and was a war correspondent during World War II (1939–1945). Slessor counted Norman Lindsay, Hugh McCrae and Jack Lindsay among his friends.
The bulk of Slessor's poetic work was produced before the end of the Second World War. His poem "Five Bells" – relating to Sydney Harbour, time, the past, memory, and the death of the artist, friend and colleague of Slessor at Smith's Weekly, Joe Lynch – remains probably his best known poem, followed by "Beach Burial", a tribute to Australian troops who fought in World War II.
In 1965, Australian writer Hal Porter wrote of having met and stayed with Slessor in the 1930s. He described Slessor as:
"...a city lover, fastidious and excessively courteous, in those qualities resembles Baudelaire, as he does in being incapable of sentimentalizing over vegetation, in finding in nature something cruel, something bordering on effrontery. He prefers chiselled stone to the disorganization of grass".
Slessor married Noela Glasson on 18 August 1922; she was 28, and they lived in Chatswood until she died of cancer in 1945.
He married Pauline Wallace in 1951; and a year later celebrated the birth of his only child, Paul Slessor, before the marriage dissolved in 1961.
He died alone and suddenly of a heart attack on 30 June 1971  at the Mater Misericordiae Hospital, North Sydney.
