Eva Winther was a Liberal People's party parliamentarian and a cabinet minister who was responsible for equalities and immigration matters during the 1978-1979 period.

Eva Winther was born in Stockholm in 1921. Her parents were Captain Martin Fornander and Gunhild Fornander. She trained as a paediatric nurse and was elected onto the Kiruna town council as a Liberal People's party representative in 1966 and remained in post until 1976. She also held local posts in Fredrika-Bremer-Förbundet (association) and in the Rädda Barnen (Save the Children) organisation.

Eva Winther was elected onto the Norrbotten county council and into parliament during the 1976 election. As a parliamentarian her roles included being chair of the labour market committee from 1977-1978 and she served as a member of the same committee from 1979–1982. In the autumn of 1978 she was appointed as a cabinet minister within the new Liberal People's party government where she became responsible for immigration and equalities matters.

During the negotiations which led to the formation of a conservative government in 1976 the Liberal People's party had successfully pushed through their demand for an equalities law and to establish an ombudsman for equalities issues. The three-party conservative government had not managed to bring forward a parliamentary proposal before it resigned in 1978. Now it fell to Eva Winther to present the first proposal in parliament. It was knocked back, however, as a number of male parliamentarians of the Moderate and Centre parties – including the leader of the Centre Party, Olof Johansson – abstained from the vote or voted with the Social Democratic party in opposition. It was not until Eva Winther’s next parliamentary mandate that parliamentary reform was introduced.

Following the resignation of the conservative government in 1981 Eva Winther was returned to parliament but lost her place in the 1982 election. She served as a member of the Halland county council from 1985–1991, during which period she was the deputy chair of the council from 1988–1991.

Eva Winther died in 2014. She is buried at The Woodland Cemetery in Stockholm.
