Yes, a Prius can be jump-started, but with some important precautions:

Use the Correct Procedure:
Locate the Jump-Start Terminals: Unlike most cars, the Prius has a jump-start terminal under the hood usually near the fuse box where you can connect jumper cables.
Connect the Jumper Cables: Connect the positive terminal of the 12V battery in the other car to the Prius positive terminal, and the negative terminal of the other car to a ground point metal part of the engine block in the Prius.
Avoid Directly Jump-Starting the Hybrid System: Never attempt to jump-start the hybrid battery directly. Always focus on the 12V auxiliary battery.
Safety First: Be sure to follow the correct order when connecting and disconnecting the cables to avoid damage to the Prius electrical system.
