The International Four Day Marches Nijmegen (Dutch: Internationale Vierdaagse Afstandsmarsen Nijmegen) is the largest multiple day marching event in the world. It is organised every year in Nijmegen, Netherlands in mid-July as a means of promoting sport and exercise. Participants walk 30, 40 or 50 kilometers daily depending on their age and gender, and, on completion, receive a royally approved medal (Vierdaagsekruis). The participants are mostly civilians, but there are also a few thousand military participants.

The "Vierdaagse" (Dutch for "four day march") is an annual walk that has taken place since 1909, being based at Nijmegen since 1916. In 2016 they celebrated the 100th edition (noting that during the 1st and 2nd world war, the marches were curtailed.) Depending on age group and category, walkers have to walk 30, 40 or 50 kilometers each day for four days. Originally a military event with a few civilians, it now is a mainly civilian event. Numbers have risen in recent years, with over 40,000 taking part – including about 5,000 military. It is now the world's largest walking event. Due to crowds on the route, since 2004 the organizers have limited the number of participants. The first day of walking is always the 3rd Tuesday in July. Many participants take part every year, including several that have taken part in 50, and even 60 different annual marches.

Each day of the marches is named after the biggest town it goes through. Tuesday is the day of Elst, Wednesday the day of Wijchen, Thursday the day of Groesbeek and Friday the day of Cuijk. The routes always stay the same unless there is a specific need to change, as it did in 2007 (route changed in 2006 but cancelled) when the walkers went through the Waalkade on Wednesday for the first time since the original route got too crowded and walkers had to wait for over an hour at some times. 2006 was the first year to be cancelled in 90 years (apart from WW II). After the first day's march there were thousands of drop-outs and two deaths because of extreme heat.

Following the 2006 cancellation, it was decided that in future the organising committee would adjust the start time/distance/finish time to manage the event, instead of outright cancellation. The 2016 centenary event responded to unusually hot conditions by adjusting the starting times, and/or increasing the valid finishing time to reflect the difficulty of course.
