Doug Ithier (born 20 July 1974) is an Australian footballer who played for Perth Glory, Walsall, and throughout Asia including Malaysia, Singapore, Indonesia, and China. Ithier was widely regarded as a tough tackling, no nonsense defender, who was great in the air and would score long range goals and free-kicks despite playing most of his career as a centre-back.
 Douglas Edward Ithier was born on 20 July 1974, in Middle Swan, Western Australia, Australia, and is the first son of Douglas Rudolf Ithier (a Mauritius born immigrant) and Mary Thelma Martain (née Ithier).

In 1992 he won the Fairest and Best player for the whole SWSA 2nd Division mens competition as a 15 year old playing in defence as a sweeper.
 From the age of 4 until 17, Ithier played as a centre-forward scoring goals in all ways and was particularly good in the air heading from set pieces. But he was signed to his first professional contract as a centre-back after he was told by his Floreat Athena manager Eric Williams when signing that he was a good Striker, but would only make money as a defender.

 As club co-captain, Ithier won the 1996 Floreat Athena Fairest and Best player and was voted 4th Best Player in the WA State League competition which led to Ithier being invited to trial with the newly formed Perth Glory and subsequent signing after 2 weeks impressing then coach Gary Marocchi.

Alan Vest once described Ithier as the "Best Header" of the ball in all Malaysia and named him Captain of the side in Billy Bone's absence. Ithier's form in Malaysia earned him the trial with Blackburn Rovers F.C.
