Future Technology Devices International Limited, commonly known by its acronym FTDI, is a Scottish privately held fabless semiconductor device company, specialising in Universal Serial Bus (USB) technology.

It develops, manufactures, and supports devices and their related cables and software drivers for converting USB signals to and from various protocols, including RS-232/TTL serial (to provide support for legacy devices on modern computers lacking an accessible UART) and inter-chip communication bus protocols (e.g. SPI, I²C, JTAG, or GPIO) to interface with chips like microcontrollers, flash memory, and FPGAs.

The company also provides application-specific integrated circuit (ASIC) design services, and consultancy services for product design, specifically in the realm of electronic devices.
