The Uddevalla Suffrage Association was founded in Uddevalla, Sweden, with the purpose of bringing about universal suffrage.

The Uddevalla Suffrage Association was a late-19th-century political movement founded in Uddevalla, Sweden. Local historians and the Swedish Social Democratic Party consider it the first political predecessor of the Swedish labour movement in the province of Bohuslän. Its purpose was to bring about universal suffrage in Sweden: At the time, suffrage in the country was restricted to men and based on personal wealth, therefore excluding most of the urban and rural working class from the electoral process. The Uddevalla Suffrage Association was one of many groups throughout Sweden that helped bring democratic thought into the common discourse and make way for the political breakthrough of the labour movement.

Uddevalla is a town in Västra Götaland County, Sweden. It’s the seat of Uddevalla Municipality. In 2015, it had a population of 34,781, making it the largest town fully in Bohuslän. Uddevalla is located where the river Bäveån opens up into Byfjorden, a fjord in the south-eastern part of Skagerrak.

Universal suffrage or universal franchise ensures the right to vote for as many people bound by a government's laws as possible, as supported by the "one person, one vote" principle. For many, the term universal suffrage assumes the exclusion of the young and non-citizens. At the same time, some insist that more inclusion is needed before suffrage can be truly universal. Democratic theorists, especially those hoping to achieve more universal suffrage, support presumptive inclusion, where the legal system would protect the voting rights of all subjects unless the government can clearly prove that disenfranchisement is necessary. Universal full suffrage includes both the right to vote, also called active suffrage, and the right to be elected, also called passive suffrage.
