Jane Barbro Iréne Cederqvist (1 July 1945 – 15 January 2023) was a Swedish freestyle swimmer.

Within a few years she became a world top freestyle swimmer,[3] and won a bronze medal at the 1958 Swedish Junior Swimming Championships.

In 1970 she received her BA and in 1980 a PhD in history with a thesis titled Arbetare i strejk: studier rörande arbetarnas politiska mobilisering under industrialismens genombrott: Stockholm 1850–1909 (Workers on Strike: The Political Mobilisation of the Working Class in Stockholm 1850–1909).

Cederqvist had long wanted to become directly involved with history and was first excited with this job, but later became frustrated with the lack of funds and moved to the Ministry of Finance, where between 1999 and 2002 she acted as director-general of the Swedish Fortifications Agency and then worked as a tax analyst.

[3][7] Cederqvist died after suffering from motor neurone disease on 15 January 2023, at the age of 77.
