Sint Joost (Limburgish: Sint-Joas) is a Dutch village in the municipality of Echt-Susteren.

The village was first mentioned in 1294 or 1295 as "De curte Sancti Judoci", and refers to Saint Judoc.

[3] Sint Joost is a linear settlement which developed around a Valliscaulian monastery.

[4] The area of Sint Joost is frequently raided by the so-called "Buckriders" (Bokkenrijders) between 1730 and 1780.

On 20 and 21 January 1945 the village was largely destroyed during the liberation by the British troops during Operation Blackcock.
