Johan (Jan) Anders Jägerhorn af Spurila (1752-1825) was a Finnish nobleman born on 8 April 1757 in Helsinki county, at that time a part of Sweden.
He was the eldest son of lieutenant colonel Fredrik Anders Jägerhorn and Ulrika Sofia Brunow.
Colonel Fredrik Adolf Jägerhorn, vice commander of the Sveaborg fortress in 1808 was Johan Anders' brother.
The Jägerhorn af Spurila noble family tree can be documented to 15th century Finland with legends - inspired by the Song of Roland - going back to the 12th century when Swedish crusader king Eric the Saint of Sweden came to Finland and made an early ancestor of the family squire of the king.
Johan Anders Jägerhorn was the founder and leader of a secret order called Walhalla-orden with its seat in the Suomenlinna fortress.
