Socket FM1 is a CPU socket for desktop computers used by AMD early A-series APUs ("Llano") processors and Llano-derived Athlon II processors. It was released in July 2011. Its direct successors are Socket FM2 (September 2012) and Socket FM2+ (January 2014), while Socket AM1 (January 2014) is targeting low-power SoCs.

For available chipsets consult Fusion controller hubs (FCH).
