Nintendo Software Planning & Development Division, commonly abbreviated as Nintendo SPD, was a Japanese research, planning and development division owned by Nintendo and housed inside the Nintendo Development Center in Kyoto, Japan. The division had two departments: Software Planning & Development Department, which primarily co-produced games with external developers; and Software Development & Design Department, which primarily developed experimental and system software. The division was created during a corporate restructuring in September 2003, with the abolition of the Nintendo R&D1 and Nintendo R&D2 departments.

Nintendo Research & Development No. 1 Department was a division of Nintendo, and is its oldest development team. Its creation coincided with Nintendo's entry into the video game industry, and the original R&D1 was headed by Gunpei Yokoi. The developer has created several notable Nintendo series such as Metroid, Mario Bros. and Donkey Kong.
