John Donvan (born circa 1955) is a correspondent for ABC News Nightline, and was an occasional substitute anchor for Ted Koppel.
Donvan has served over a career of more than two decades in the following capacities for ABC News: Chief White House Correspondent, Chief Moscow Correspondent, Amman Bureau Chief, Jerusalem Correspondent, and Correspondent for the ABC News Magazine Turning Point.
More recently, Donvan has received positive reviews for his work covering the war in Iraq as a unilateral reporter, for which the Chicago Sun Times named him one of the ten war stars. He has made several return trips to Baghdad since.

Career History
He attended Regis High School (New York City) and graduated magna cum laude from Dartmouth College and the Columbia University Graduate School of Journalism. He and his wife, Dr. Ranit Mishori, have a son, Ben, and a daughter, Noa and a dog, Hee Hee Loo.
The first part of Donvan's career was shaped as a foreign correspondent, beginning at age 25 for ABC Radio in 1980. In 1982, the network promoted him to television. He was assigned to Jerusalem on the West Bank and the rest of the Arab world.
From 1985 to 1988, he worked for CNN, as a London-based correspondent, covering Europe, the Middle East, and Africa. His live reporting on the U.S. bombing of Libya was likened to the work of Edward R. Murrow by the New York Daily News.
Donvan rejoined ABC in 1988 and has been there ever since. Based in London, and later Moscow, he covered nearly all of the major news events overseas through the 1980s and the 1990s. This includes; the collapse of Communism (he was in Red Square the night the Soviet flag came down, and in Romania when Nicolae Ceauşescu was arrested); the Iran-Iraq War; both Persian Gulf Wars; two Royal Weddings; the assassination of Anwar Sadat; the bombing of the marine barracks in Beirut; and the end of the nuclear arms race.
Donvan returned to New York in 1993, where he contributed to ABC News' magazine programs and World News Tonight, and occasionally served as an anchor on Good Morning America and weekend news broadcasts. In 1997, he was assigned to the network's Washington DC bureau, and the White House beat, covering the campaign finance scandal and the president's travels abroad. He joined Nightline in 1998 and continues as one of that program's small cadre of correspondents. He is an occasional substitute anchor for Ted Koppel, and hosted many interviews for Nightline's production of UpClose.
In May 2007 John Donvan became the primary anchor of the Nightline Webcast, a daily webcast which previews the night's show and offers a behind the scenes look at Nightline.
