+## Set Queue Priority for Workflows
+
+Use priority to control which workflows run first. Lower numbers = higher priority.
+
+**Incorrect (no priority control):**
+
+```python
+queue = Queue("tasks")
+
+# All tasks treated equally - urgent tasks may wait
+for task in tasks:
+    queue.enqueue(process_task, task)
+```
+
+**Correct (with priority):**
+
+```python
+from dbos import Queue, SetEnqueueOptions
+
+# Must enable priority on the queue
+queue = Queue("tasks", priority_enabled=True)
+
+@DBOS.workflow()
+def process_task(task):
+    pass
+
+def enqueue_task(task, is_urgent: bool):
+    # Priority 1 = highest, runs before priority 10
+    priority = 1 if is_urgent else 10
+    with SetEnqueueOptions(priority=priority):
+        queue.enqueue(process_task, task)
+```
+
+Priority behavior:
+- Range: 1 to 2,147,483,647 (lower = higher priority)
+- Workflows without priority have highest priority (run first)
+- Same priority = FIFO order
+- Must set `priority_enabled=True` on queue
+
+Example with multiple priority levels:
+
+```python
+queue = Queue("jobs", priority_enabled=True)
+
+PRIORITY_CRITICAL = 1
+PRIORITY_HIGH = 10
+PRIORITY_NORMAL = 100
+PRIORITY_LOW = 1000
+
+def enqueue_job(job, level):
+    with SetEnqueueOptions(priority=level):
+        queue.enqueue(process_job, job)
+```
