John Sydney "Syd" Millar, CBE, MBE (born 23 May 1934) was an Irish rugby union prop who played international rugby for Ireland and the British Lions. After retiring from playing rugby he became a rugby coach and later rugby administrator, becoming chairman of the Irish Rugby Union in 1995 and from 2003 until 2007 was the chairman of the International Rugby Board.
Syd Millar was born in Ballymena in Ireland. He played for Ballymena RFC and represented Ireland in the pack, winning 37 caps as a prop. In addition, he played nine times for the British and Irish Lions. Millar also coached the successful 1974 British Lions tour to South Africa and managed the 1980 British Lions tour to South Africa. Before becoming involved with rugby union's governing body, he served as manager of the Irish national side at the 1987 World Cup.
Millar became the president of the Ulster Rugby Union in 1985, and was appointed as one of the representatives of the Irish Rugby Football Union (IRFU) on the IRB Council in 1992. He became president of the IRFU in 1995,  and was also chairman of the British and Irish Lions from 1999 to 2002.
In 2002 the IRB Chairman Vernon Pugh became seriously ill. Millar was appointed as Vice-Chairman of the Board of the IRB on 16 September 2002, replacing New Zealander Rob Fisher. He took on the role of interim chairman after the death of Pugh in 2003.
Millar was elected as the IRB chairman in late 2003 to a four-year term commencing in 2004. He presided over a governance restructure and new strategic plan for the IRB, and was influential in the continued lobbying for Rugby sevens inclusion in the Summer Olympics. He stepped down from his posts at the IRB and the IRFU following the 2007 World Cup, and was succeeded as IRB chairman by Bernard Lapasset.
Millar was awarded an Honorary Science Doctorate by the University of Ulster in 1992, and was inducted into the International Rugby Hall of Fame in 2003. He received a CBE in 2005 having previously been awarded the MBE.
