Ivor William Evans (24 July 1887 – 25 April 1960) was an Australian businessman. As a 14-year-old schoolboy, he was one of five winners of the 1901 Federal Flag Design Competition, held to design a national flag for Australia.

Evans was born on 24 July 1887 in Carlton, Victoria, the third son of Sally Clara (née Russell) and Evan Evans. His father, an immigrant from Wales, was the founder of a firm that manufactured canvas goods. Evans attended Princes Hill State School before completing his education at the New College on a scholarship. He joined the Commercial Bank of Australia in 1904 and subsequently became manager of its Chillingollah branch.^[1]

At the age of 17, he played a single game of senior Australian rules football with the St Kilda Football Club during the 1904 VFL season.^[2]

In 1901, aged 13, Evans submitted a design to the Federal Flag Design Competition held by the Barton government to choose a national flag for Australia. He shared the £200 prize with four others, including Annie Dorrington, as their designs were nearly identical.^[1] One of the five judges, John Evans,^{[lower-alpha 1]} praised the technical accuracy of Evans' design in relation to his sizing of the stars of the Southern Cross based on their brightness. The winning entrants were invited to the Royal Exhibition Building to watch the first unveiling of the new flag.^[3]

In 1951, Evans wrote to Prime Minister Robert Menzies suggesting that each school should be presented with an Australian flag to mark the 50th anniversary of Federation, which resulted in over 10,000 flags being distributed.^[4] He continued to give interviews about the flag until a year prior to his death.^[3]
