Rijsoord was a separate municipality until 1855, when it merged with Ridderkerk. Between 1846 and 1855, it was named "Rijsoort en Strevelshoek" after a merger with the smaller municipality of Strevelshoek. The current village is largely located north of the Waaltje (little Waal) river, outside the area of the former municipality.
The village had its day in history on 15 May 1940, when the Dutch Commander-in-Chief General Henri Winkelman had to sign the surrender to the German invaders, after four days of fighting in World War II. The formality took place in a school building in Rijsoord, now a museum.
