The Christian National Trade Union Federation (Dutch: Christelijk Nationaal Vakverbond, CNV) is a federation of trade unions of the Netherlands.

The CNV was founded on 13 May 1909, in Arnhem as a federation of several Christian unions.^[2] It was founded in reaction to the socialist Dutch Confederation of Trade Unions (NVV), which was founded in 1906. The CNV was more moderate than the NVV. It opposed the idea of class struggle and instead oriented itself towards a corporatist model of the economy. It was an interconfessional union, intended to represent both Protestant and Roman Catholic workers.

In 1912, however, the Roman Catholic bishops spoke out against interconfessional unions. All Roman Catholics left CNV and founded a separate Roman Catholic union, the RKWV "Rooms-Katholieke Werklieden Verbond" (Roman Catholic Workers' Union). The CNV orientated itself towards the Protestant Anti-Revolutionary Party, with which it formed the Protestant pillar.

After World War II, the corporatist model, which the CNV advocated was introduced in the Netherlands, this was combined with a strong welfare state. Unions received more influence in Dutch politics: the CNV became part of the Social-Economic Council an advisory board of government composed of representatives from unions, employers' organisations and independent scientists.

Because of the depillarisation of Dutch society and the rising political polarisation between left and right, the three major unions, the socialist NVV, the Protestant CNV and the Dutch Catholic Trade Union Federation (NKV) began to open talks in order to found one single federation of Dutch unions. In 1974 the CNV left those talks. In 1976 the NVV and NKV merged to form the Federation of Dutch Trade Unions (FNV), which was led by Wim Kok.

The most important function of CNV is the CAO-talks, over wages and secondary working conditions, it holds with the employers' federations. It also advises government via the Social Economic Council in which other unions, the employers' organisations and government appointed experts also have seats.

The CNV started out as a moderate, Christian-democratic union, which was opposed to class struggle and workers' ownership of the means of production. Gradually, however, it oriented itself towards cooperation with the employers' organisations and a corporatist model of the economy. The CNV still prefers cooperating with employers over strikes.

It has founded a youth union, CNV-jongeren to address the issues of the ageing population and it has campaigned on issues of international cooperation with a separate organisation called CNV international.

The CNV is a federation of three affiliated trade unions. Its board is formed by four daily board members (a chairman, a vice-chairman, a secretary and a treasurer), and the chairs of the affiliated unions. The CNV has around 355,000 members. The current chair is Maurice Limmen. Although the CNV is formally independent of other organisations there are strong ideological and personal links with the CDA. Former CNV vice chair Aart-Jan de Geus served between 2002 and 2007 as CDA minister of Social Affairs and Employment for instance.
