A battery grip is an accessory for many cameras, especially digital single-lens reflex (DSLR) models due to their power requirements. It attaches to the camera body and provides a compartment to hold additional batteries to increase the available power for the camera. Often, the camera body will use rechargeable lithium-ion batteries in a proprietary format, while the battery grip will accept standard AA or CR-V3 batteries for greater flexibility.

A battery grip also provides a more comfortable and secure way of holding the camera, and usually makes it easier to orient the camera vertically for portrait photography. Some battery grips have additional shutter buttons and controls.

Most battery grips are designed to fit only one or a few specific camera models, since they must match the body's shape, connectors, and power requirements.
