Shenzhen Nanjing Technology Co., Ltd. (深圳市南晶科技有限公司) is a company that was founded in 2002 (although their website states 2003) in Shenzhen, mainland China, and that formerly developed Chinese-language turn-based RPGs for the Famicom. They are one of the only Famicom pirate developers known to still exist, along with Waixing.

Today, Nanjing is no longer known to develop its own games, and operates instead as a manufacturer of consoles, mostly Famiclone and other handhelds, such as the PVT series.
