Harald "Slaktarn" Andersson (2 April 1907 – 18 May 1985) was a Swedish discus thrower.

[4][3] He broke Paul Jessup's world record of 51.73 m twice in one competition (a dual meet between the Swedish and Norwegian teams in Oslo) on 25 August 1934, throwing first 52.20 m and then 52.42 m;[5] the latter mark was officially ratified by the IAAF.

[6] At the European Championships in Turin two weeks later Andersson threw 50.38 m and won by more than three meters from Paul Winter and István Donogán.

[7] Andersson lost his world record in April 1935, when Germany's Willy Schröder threw 53.10 m in Magdeburg;[6] however, he remained the world's top thrower, as Schröder was less consistent at a high level and suffered from health problems over the summer.

[5][10] He was a leading favorite for the 1936 Summer Olympics in Berlin, but injured himself before the Games;[3] he attempted to throw in the qualification, but only managed about 38.5 metres and failed to qualify for the final.
