Daphne Akhurst Cozens (Daphne Jessie Akhurst; 22 April 1903, in Ashfield, New South Wales – 9 January 1933, in Sydney) was an Australian tennis player. According to Wallis Myers (Daily Telegraph, Daily Mail), she was ranked World No. 3 in 1928.
The second daughter of Oscar James Akhurst, a lithographer, and his wife Jessie Florence (née Smith), Daphne Akhurst won the women's singles title at the Australian Championships five times, in 1925, 1926, 1928, 1929, and 1930. She is tied for third (with Serena Williams) on the list of most women's singles titles at the Australian Championships; behind only Margaret Court with eleven titles and Nancye Wynne Bolton with six titles. She won the women's doubles title at the Australian Championships five times: in 1924 and 1925 with Sylvia Lance Harper, in 1928 with Esna Boyd Robertson, and in 1929 and 1931 with Louie Bickerton. She and Marjorie Cox were the runners-up in 1926.
Akhurst won the mixed doubles title at the Australian Championships four times: in 1924 and 1925 with Jim Willard, in 1928 with Jean Borotra, and in 1929 with Gar Moon. She and Willard were the runners-up in 1926. She and her partner Jack Crawford reached the mixed doubles final at Wimbledon in 1928, but lost to the team of Elizabeth Ryan/Patrick Spence, 7–5, 6–4.
On 26 February 1930 at St Philip's Church of England, Sydney, Daphne Akhurst married Royston Stuckey Cozens, a tobacco manufacturer, and retired from serious competition soon after winning the Australian ladies' doubles championship in 1931. They had one son, Don.
Daphne Akhurst Cozens died on 9 January 1933, aged 29, from an ectopic pregnancy and was cremated.
The trophy presented each year to the winner of the women's singles at the Australian Open is named the Daphne Akhurst Memorial Cup in her honour. She was inducted into the Australian Tennis Hall of Fame on Australia Day (26 January), 2006. She was inducted into the International Tennis Hall of Fame in 2013.
