Roni Bar-On (Hebrew: רוני בר-און, born 2 June 1948) is an Israeli politician and lawyer.

In 1997 he was appointed Attorney General, but resigned as a consequence of heavy criticism related to the 'Bar-On–Hebron' scandal, which involved allegations against chief officials that they recommended Bar-On to the position for personal reasons.

Prior to his political career, Bar-On served, among others, as Chairman of the Council for the Organisation of Sport Gambling (1998–2001), member of the Central Committee of the Israel Bar (1995–2003) and the Jerusalem Regional Committee of the Israeli Bar, as well as a member of the Council for the Administrative Courts, the Advisory Commission to the Government Companies Authority and the Public Defenders Commission.

He was also considered for the post of Justice Minister after Haim Ramon's conviction for sexual harassment, but withdrew his candidacy on 4 February 2007.

As a part of a coalition reshuffle, Bar-On was then elected for the position of Head of Foreign Affairs and Defense Committee.
