Perfect Dark (パーフェクトダーク) is a peer-to-peer file-sharing (P2P) application from Japan designed for use with Microsoft Windows. It was launched in 2006. Its author is known by the pseudonym Kaichō (会長, "The Chairman"). Perfect Dark was developed with the intention for it to be the successor to both Winny and Share software.[4] While Japan's Association for Copyright of Computer Software reported that in January 2014, the number of nodes connected on Perfect Dark (24000) was less than on Share (44000), but more than on Winny (12000),[5] Netagent in 2018 reported Winny being the largest with 50 000 nodes followed by Perfect Dark with 30 000 nodes followed by Share with 10 000.[6] Netagent asserts that the number of nodes on Perfect Dark have fallen since 2015 while the numbers of Winny hold steady. Netagent reports that users of Perfect Dark are most likely to share books/manga.

As of version 1.02 (2008), code-named "Stand Alone Complex", there is support for the program to run in English, an option that can be selected when the program is installed.
