Violet Ethel Mary Walrond (27 February 1905 – 17 December 1996) was a New Zealand swimmer, who represented New Zealand at the 1920 Summer Olympics at Antwerp at the age of 15, making her New Zealand's first female Olympic athlete. In the 100 metre freestyle race she came 5th, and in the 300 metre freestyle race she came 7th (although New Zealand newspapers said she was 6th, and some publications said she did not start due to illness). She used the crawl style. This is the only Olympics to have a 300 metres women's freestyle race; in 1924 it became the 400 metres freestyle like the men's race.
Her father Cecil 'Tui' Walrond (an excellent swimmer, who had received a Royal Humane Society award for rescuing 11 people from drowning) accompanied her as her chaperone and unofficial team trainer. Violet and her younger sister Edna retired from competitive swimming in 1923. Violet was 18, and Joseph Romanos was told by Violet that they retired on orders from their father, as he felt that we were too much in the public eye. He also forbade them from cutting their long hair short. Violet would have been a likely selection for the 1924 Olympics.
She married Harold Robb in 1933, and died in 1996 aged 91, in Papakura, Auckland.
