Oskar Karl Henningsson (born 10 August 1985) is a Swedish professional golfer.
Henningsson was born in Eksjö and later moved to Gränna. He turned professional in 2004.
Henningsson reached the final stage of the European Tour Qualifying School in 2004 to gain a place on the second tier Challenge Tour for 2005. He had little success, and lost his playing status after just two seasons. Having mostly played in minor tournaments in Sweden for two years, he returned to the qualifying school at the end of 2008. He came out with the number one card for the European Tour, becoming the first player ever to be medalist at qualifying school having gone through all three stages.
In 2009, Henningsson won his first European Tour title at the Moravia Silesia Open in the Czech Republic. He came from behind in the final round with a 5 under par 67 to finish 2 strokes ahead of overnight leader Steve Webster and Sam Little.
