Anthony Thiessen (25 May 1942 – 3 September 2019) was an Australian rules footballer who played with Melbourne, Carlton and North Melbourne in the Victorian Football League (VFL).
Thiessen was a key forward, recruited to Melbourne from Sandy Bay. He made seven appearances in the 1963 VFL season and was then delisted, missing out on a chance to be part of Melbourne's 1964 premiership.[2] After playing for Carlton in 1964, he was cleared to North Melbourne where he would be used as a midfielder.[3] It was his only year at North Melbourne, which gave him the unusual distinction of having played with three separate clubs in a three-season career. He also played with the Waverley Football Club, in the Victorian Football Association.[4]
James Thiessen, his son, was a member of Adelaide's 1998 AFL premiership team.
