Van Zanten is a Dutch surname meaning "from Xanten".
 Notable people with the surname include:
Partnair Flight 394 was a chartered flight which crashed on 8 September 1989 off the coast of Denmark 18 km north of Hirtshals.
 All 50 passengers and 5 crew members on board the aircraft perished, making it the deadliest civilian aviation accident involving an all-Norwegian airline company.
 It was also the highest death toll of any aviation accident involving a Convair 580, and the biggest aeroplane accident in Denmark.
 It was caused by use of unapproved aircraft parts in repairs and maintenance.
On March 27, 1977, two Boeing 747 passenger jets, KLM Flight 4805 and Pan Am Flight 1736, collided on the runway at Los Rodeos Airport (now Tenerife North Airport), on the Spanish island of Tenerife, Canary Islands, killing 583 people in the deadliest accident in aviation history.
Vnukovo Airlines Flight 2801 was an international charter flight that, on 29 August 1996 at 10:22:23 Central European Summer Time, crashed in Operafjellet, Svalbard, Norway during the approach to Svalbard Airport, Longyear.
 All 141 people aboard the Tupolev Tu-154M were killed, making it the deadliest aviation accident ever in Norway.
 The accident was the result of a series of small navigational errors causing the aircraft to be 3.7 km from the approach centerline at the time of impact.
 The accident was investigated by the Accident Investigation Board Norway with assistance from the Interstate Aviation Committee and became known as the Operafjell Accident (Norwegian: "Operafjell-ulykken" ).
The Chez Jo Goldenberg restaurant attack was a bombing and shooting attack on a Jewish restaurant in Paris's Marais district, on 9 August 1982 carried out by the Abu Nidal Organization, a group that splintered from Fatah.
 Two assailants threw a grenade into the dining room, then rushed in and fired machine guns.
 They killed six people, including two Americans, Ann Van Zanten, a curator at the Chicago Historical Society, and Grace Cutler, and injured 22 others.
 Mrs. Van Zanten's husband, David, an art history professor at Northwestern University, was among the injured.
 BusinessWeek later said it was "the heaviest toll suffered by Jews in France since World War II."
 The restaurant closed in 2006 and former owner Jo Goldenberg died in 2014.
Veldhuyzen van Zanten is a Dutch family name, also spelled as Veldhuijzen van Zanten.

Lauda Air Flight 004 was a regularly-scheduled international passenger flight between Bangkok, Thailand and Vienna, Austria.
