The Swedish Road Workers' Union (Swedish: Svenska Vägarbetareförbundet, SVaf) was a trade union representing road and railway maintenance workers in Sweden.
It immediately affiliated to the Swedish Confederation of Trade Unions, and secured its first collective agreement in 1924.
It was originally based in Krylbo in central Sweden, but moved its headquarters to Stockholm in 1939.
In 1949, it members involved in construction were transferred to the new Swedish Building Workers' Union.
The following year, it merged into the new Swedish National Union of State Employees.
