Wilm Dedeke (c. 1460 – c.1528) was a late gothic painter from Northern Germany.
Dedeke completed the Altar of St. Luke (Lukas-Altar) at the Hamburg Mariendom in 1499 for the Hamburg Guild of Saint Luke.
It had been left unfinished by his late colleagues Hinrik Bornemann and Absolon Stumme; Dedeke married the widow of the latter man.
In 1502 he attained the title of Master of the Brotherhood of St.
[1] He has been identified with the anonymous "Master of the Halepagen Altar".
