Tommy Raudonikis was an Australian rugby league footballer and coach. He played 40 International games and World Cup games as an Australian representative halfback and captained his country in two matches of the 1973 Kangaroo tour. Known as a genuine hard man, Tommy instilled that mettle into his coaching to produce ruthless sides that took no prisoners and played a brutal style of rugby league.

Raudonikis was born in Bathurst, New South Wales, the son of a Lithuanian immigrant father and a Swiss immigrant mother. He grew up in Cowra. He said, "Mum and Dad migrated over here in 1950. Mum was pregnant with me on the boat, and I was born at the migrant camp." He joined the Royal Australian Air Force (RAAF) as an engineering apprentice in 1967 and spent three years under training at RAAF Base Wagga.

Raudonikis played 201 games for the Western Suburbs Magpies between 1969 and 1979. Raudonikis quickly established himself of one of the Leagues top players when in 1972 he won the Rothmans Medal, as judged by the NSWRL referees as the best and fairest player in the competition. Led by Raudonikis with the likes of Graeme O'Grady, Les Boyd and John Donnelly, the Magpies enjoyed several finals appearances in the late 70's, including winning the 1977 Amco Cup and the Minor Premiership in 1978. Raudonikis epitomised the "Fibros versus Silvertails" rivalry with the Manly-Warringah Sea Eagles stoked by Western Suburbs coach Roy Masters. However, Premiership success eluded the Lidcombe based club and Raudonikis.

Along with fellow Magpies Graeme O'Grady and Steve Blythe, Raudonikis moved from Western Suburbs to the Newtown Jets, playing 37 games in three seasons between 1980 and 1982. He captained the Jets to the 1981 NSWRL Grand Final against Parramatta. He scored a try early in the second half of the match but Newtown would eventually be defeated 20 - 11. Tommy then moved to Queensland in 1983 where he was captain-coach of the Brothers club in Brisbane. In September 2004 he was named in the Western Suburbs Magpies team of the century. Raudonikis was Western Suburbs club captain from 1971 to 1979, and was Newtown club captain from 1980 to 1982

Raudonikis was first selected in an Australian squad in 1971 behind Souths halfback Bob Grant and made his run on debut in 1972 against the Kiwis (the same year he won the Rothmans Medal for best club player for the season). He was the regular Test halfback for the next six years. He made Test appearances up until 1980 by which time he was being challenged by Greg Oliphant and Steve Mortimer. He was the captain of the New South Wales State of Origin team in the inaugural 1980 "Origin" contest. Queensland won 20-10 with Raudonikis, in his one-and-only Origin appearance. Having been knocked out early in the game he would have little impact despite scoring a late try for New South Wales.

Raudonikis' final playing year was in a captain coach role at Brisbane Brothers in 1983. From 1985-88, he coached Ipswich Jets, guiding the Jets to their first Brisbane Rugby League Grand Final appearance in 1988. In 1990, his first season as Brisbane Norths coach, Raudonikis led the club to the 1990 Brisbane Rugby League Grand Final, the Devils just falling short 16-17. Returning to Sydney, he was coach of the Western Suburbs Magpies from 1995 until the formation of the Wests Tigers joint venture with the Balmain Tigers at the end of 1999. He had some initial coaching success making the finals in 1996, but Wests were ultimately unable to build on this and only won six games in their final two seasons.

Raudonikis coached the Blues in the 1997 and 1998 series. In those series he entered State of Origin folklore when he introduced the "cattle dog" call to which NSW players responded by breaking from the scrum with fists flying, resulting in two infamous all-in-brawls.

In February 2008, Raudonikis was named in the list of Australia's 100 Greatest Players (1908–2007) to celebrate the code's centenary year in Australia. Also in 2008, the Western Suburbs Magpies celebrated their centenary by inducting six inaugural members, including Raudonikis, into the club's Hall of Fame. Raudonikis' hospitalisation in August 2006 for a heart bypass operation received national coverage and drew messages of support from a spectrum of famous former players including Wests icon Arthur Summons.

Raudonikis was reported to have inoperable cancer in April 2019. Two years later, he died of the disease on the Gold Coast, Queensland, six days short of his 71st birthday.
