Thomas Welbourn "Tim" Wall (13 May 1904 – 26 March 1981) was an Australian cricketer who played eighteen Test matches between 1929 and 1934. On his debut, he took five wickets in the second innings against England in Melbourne. Wall was a school teacher in Adelaide before and after his cricket career. He died in 1981 after a long battle with Parkinson's disease. Wall's 10–36 in February 1933 remains the best first-class figures recorded in Australia. It is also the only ten-wicket innings ever recorded for South Australia.
