The Transfer Pak is an accessory for the Nintendo 64 (N64) controller. It features a cartridge slot compatible with Game Boy or Game Boy Color (GBC) games. When plugged into the controller's expansion port, it allows for the transfer of data between supported N64 and GBC games to access additional content. The Pokémon Stadium games, with which the Transfer Pak was initially bundled for sale, also feature the ability to emulate specific Game Boy Pokémon titles for play on the N64.

The Transfer Pak was supported by 20 N64 and 64DD games released between 1998 and 2000, only six of which supported it outside of Japan. Several games which initially planned to utilize the accessory were either cancelled or had the functionality removed. A similar accessory for the 64DD, the 64 GB Cable, was also never released. As a result, while recognized as one of the first examples of connectivity between Nintendo's home consoles and handhelds, retrospective coverage of the Transfer Pak has found it largely unnecessary.
