The Transfer Pak, known in Japan as the 64 GB Pack, is an accessory manufactured by Nintendo that plugs into the Nintendo 64 (N64) controller. It allows for the transfer of data between supported N64 and Game Boy or Game Boy Color (GBC) games to access additional content. The Pokémon Stadium games, which the accessory was initially bundled with, also use it to emulate Game Boy Pokémon games on the N64.

The Transfer Pak is recognized as one of the first examples of connectivity between Nintendo's home and handheld consoles. It was supported by only twenty games released for the N64 and its 64DD expansion between 1998 and 2000, the majority of which were not released outside Japan. Several games that were initially planned to support the accessory were either cancelled or had the functionality removed before release. Digital re-releases of games with Transfer Pak support have also been inconsistent in retaining these features. As a result, retrospective coverage of the accessory has found it largely unnecessary. A similar accessory, the 64 GB Cable, was designed to use the GBC as a second screen when playing 64DD games, but it was never released.
