The Northern Islands series is a family of GPUs developed by Advanced Micro Devices (AMD) forming part of its Radeon-brand, based on the 40 nm process. Some models are based on TeraScale 2 (VLIW5), some on the new TeraScale 3 (VLIW4) introduced with them.

Starting with this family, the former ATI brand was officially discontinued in favor of making a correlation between the graphics products and the AMD branding for computing platforms (the CPUs and chipsets). Therefore, the AMD brand was used as the replacement. The logo for graphics products and technologies also received a minor makeover (using design elements of the 2010 "AMD Vision" logo). This also marks the end of the "Mobility Radeon" name in their laptop GPUs, keeping only the "M" suffix in the GPU model number to signify a Mobile variant.

Its direct competitor was Nvidia's GeForce 500 series; they were launched approximately a month apart.
