Conrad von Soest, also Konrad in modern texts, or in Middle High German Conrad van Sost or "von Soyst", (born around 1370 in Dortmund;[1] died soon after 1422) was the most significant Westphalian artist and painted in the so-called soft style of International Gothic.

[3] Conrad von Soest's main surviving works are influenced by French illuminated manuscripts and certain early Parisian examples of Early Netherlandish painting; his detailed knowledge of Parisian patterns and techniques points towards a sojourn in Paris as a journeyman in the 1380s:[citation needed] The surviving documents relevant to Conrad von Soest are: As the name 'Conrad von Soest' does not appear in the list of new citizens and as his marriage contract was written in the form reserved for Dortmund citizens, he was clearly born to a Dortmund family.

[9] The marriage contract ("Morgensprache"), made before witnesses, between "Conrad von Soest" and "Gertrude, daughter of Lambertes van Munster", is dated February 11, 1349.

According to the membership list of the Confraternity of Mary of 1396, Conrad von Soest lived in the Ostenhellweg, Dortmund's principal thoroughfare.

Since 1954, the Landschaftsverband Westfalen-Lippe (Landscape Society Westphalia-Lippe) has awarded the Konrad-von-Soest Prize for Visual Arts, endowed with 12,800 euros.
