 ```
 
+It is similar to the previous one with the difference that in this one we use region to only look for the templates of that region.
+The Instance/Kubernetes cluster where you use this data source must be in the same region.
+
+```hcl
+data "civo_template" "debian" {
+   region = "LON1"
+   filter {
+        key = "name"
+        values = ["debian"]

+   }
+    sort {

+    }
