David Byrne SC (born 6 April 1947) is an Irish Fianna Fáil politician and barrister who served as Chancellor of Dublin City University from 2006 to 2011, European Commissioner for Health and Consumer Protection from 1999 to 2004 and the Attorney General of Ireland from 1997 to 1999.^[1]

He was called to the Bar in 1970, and practiced law in the Irish and European Courts. During his student days in Dublin, he founded the Free Legal Advice Centre, a student-run organisation providing legal aid to citizens in association with the legal profession. He campaigned in favour of Irish entry into the European Community in the 1970s, and has been a keen supporter of European integration ever since.^[2]

Byrne became a Senior Counsel in 1985. He practised in both the Irish courts and the European Court of Justice, and also served as a member of the International Court of Commercial Arbitration from 1990 to 1997.

As one of the negotiators of the Good Friday Agreement in April 1998, he drafted and oversaw the major constitutional amendments required by that agreement, which were approved by Referendum in May 1998.
