The National Union of Rail, Maritime and Transport Workers (RMT) is a trade union in the United Kingdom which unionises transport workers. It has more than 80,000 members, and its current general secretary is Bob Crow. It is one of Britain's fastest growing trade unions, increasing its membership by more than a third in the first five years of Crow's leadership.
Predecessors of the RMT were among the unions which set up the Labour Representation Committee in 1900. In 2003, some Scottish branches of the RMT, affiliated to the Scottish Trades Union Congress, voted to donate some of their funds to the Scottish Socialist Party. This led the Labour Party to disaffiliate the union in early 2004. In Wales some branches supported Forward Wales, led by the former Labour Welsh Assembly member John Marek. The RMT is affiliated to the Left pressure group the Labour Representation Committee (LRC), which is named after the original LRC of 1900, and works to restore socialist principles within the Labour Party. Some local branches of the RMT, such as Grimsby, are still affiliated to their local Constituency Labour Party (CLP).
The RMT announced in March 2009 that it would be standing a slate of candidates in the 2009 European Parliament elections under the banner of No to EU – Yes to Democracy, a broad left-wing alter-globalisation coalition which aims to offer an alternative to the "anti-foreigner" and pro-business policies of the UK Independence Party. 
The RMT has applied for membership in the World Federation of Trade Unions (WFTU) in 2013.
The RMT in recent years are best known to the British public through media exposure for their on-going clashes with London Underground and its privatised contractors Metronet and Tubelines. In the early 21st century, clashes leading to industrial action costing London business millions of pounds per day and causing travel disruptions have included concerns over pay, safety, pensions and job security. In 2009, one such strike coincided with an England international match. RMT leader Bob Crow claimed that either the transport commissioner or the Mayor of London blocked an agreement with the RMT on the eve of the strike only 35 minutes after LU management had agreed to it. On 15 June 2011 the RMT announced a strike will begin on 19 June 2011, disrupting the Wimbledon Championships.
On 24 June 2011, the strikes were cancelled after London Underground reinstated the Tube driver at the centre of the dispute.
