Spring (Polish: Wiosna) was a social democratic and pro-European political party in Poland led by a former mayor of Słupsk, Robert Biedroń.

The party was founded on 3 February 2019 in Hala Torwar and ran in the 2019 European elections,[5] winning three seats.

Another proposal was to introduce a new law that would set the minimum wage at 60% of the national monthly income average.

On the environment, the party leader Biedroń stressed the importance of fighting smog by closing all mines by 2035, departing from coal and switching to renewable sources of energy.

On world view issues, Spring took a liberal stance by proposing to introduce civil partnerships for opposite-sex and same-sex couples as well as the legalisation of same-sex marriage, legalisation of abortion up to 12 weeks of pregnancy, IVF funded by the state, total separation of church and state and abolition of the so-called Church Fund.
