Henrik Klasson Fleming (15 August 1584 – 7 November 1650) was a member of the Swedish nobility and admiral, diplomat and lord marshal.

[1] He was the author of one of the first autobiographies in Swedish, a colourful depiction of his early life which he wrote for his children in a moralising purpose.

[1] Along with Privy Council members Philip von Scheiding (1578-1646) and Erik Karlsson Gyllenstierna (1602-1657) he traveled in March 1634 as envoy to the Grand Duchy of Moscow.

Later, he supplied goods to the army through trade and leasing,[4] so that by his death he had accumulated a fortune, both in wars and partly on business speculation, of which he used a large portion to benefit his people.

In 1641, Henrik Fleming had financed the construction of Virmo Church (Mietoisten kirkko) in Mynämäki, Finland.
