Select About This Mac from the Apple menu (the Apple icon in the top left), and a window will appear containing your version number. If it's 10.2.x, you're running Jaguar, if it's 10.3.x, you're running Panther, if it's 10.4.x, you're running Tiger, and if it's 10.5.x you're running Leopard (you lucky dog you).
