The Royal Dutch Swimming Federation (Dutch: Koninklijke Nederlandse Zwem Bond, “KNZB”) is the official governing body for swimming, in the Netherlands. The federation overlooks several other sports including competition swimming, open water swimming, water polo, diving and synchronized swimming. The federation is based in Nieuwegein and affiliated with the national sports body NOC*NSF. The responsibility of the KNZB is to organize and track various events. When a new organization from one of the water sports joins the KNZB they can participate in the competitions governed by the KNZB. They will then be placed on a ranking list.
The KNZB was founded on August 14, 1888 by four collaborating swim organizations. At this time the federations responsibility covered only five swim clubs 
- Arnhemse Zwemclub,
- Goudse Zwemclub,
- Hollandse Dames Zwemclub,
- Leidsche Zwem Club (later LZ 1886)
- AZ 1870 (Amsterdamse Zwemclub)
In 1888 the federation was named Nederlandse Zwem Bond (“NZB” English: Dutch Swimming Federation). In 1933, federation was renamed to the KNZB gaining the word Koninklijk (Royal in Dutch). In 1909 the KNZB joined the world swimming governing body, FINA which was established one year earlier.
Competition swimming is considered a top sport in the Netherlands where world winners such as |Pieter van den Hoogenband| and |Igne de Bruijn| have brought home Olympic success. All Dutch swimming records are ratified by the KNZB. In principle all swim clubs of the Netherlands joins the KNZB because then it has many benefits including ability to participate in competitions, discount to attend courses and liability insurance.
There are two national competitions that the KNZB governs. They are:
- National Swim Competition
- KNZB Long Distance Circuit
The objective of the National Swim Competition is for all swim clubs affiliated with the KNZB to participate in a competition against other KNZB clubs with more or less equal strength.
The KNZB Long Distance Circuit is designed to simulate swimming over an extended length. The competition promotes swimmers to practice longer distances. Simplified regulations for the individual makes the competition more attractive. 
In order to keep the games fair, all judges are trained under the material of the KNZB. This system uses a ladder style chart for grading officials. Where officials must meet certain requirements before they can move to the next level.
