Martin à Beckett Boyd (10 June 1893 – 3 June 1972) was an Australian writer born into the à Beckett–Boyd family, a family synonymous with the establishment, the judiciary, publishing and literature, and the visual arts since the early 19th century in Australia.
Boyd was a novelist, memoirist and poet who spent most of his life after World War I in Europe, primarily Britain.
His work drew heavily on his own life and family, with his novels frequently exploring the experiences of the Anglo-Australian upper and middle classes.
He was intensely involved in family life and took a keen interest in the development of his nephews and nieces and their families, including potter Lucy Beck (b.
1916), painter Arthur Boyd (1920–1999), sculptor Guy Boyd (1923–1988), painter David Boyd (1924–2011), painter Mary Nolan (1926–2016) – who was married to painters John Perceval and Sidney Nolan – and architect Robin Boyd (1919–1971).
