Trans World Radio (TWR) is a multi-national evangelical Christian media distributor.

The largest Christian media organization in the world, it uses high-powered medium wave (AM) and short wave transmitters, local FM radio stations, cable, satellite, Internet, and mobile device technologies.

TWR started in 1952, when Paul Freed set up the organization to reach Spain by broadcasting from Morocco.

Other major transmitting sites include Guam (KTWG), Bonaire,[1] Sri Lanka, Cyprus, and eSwatini (Swaziland).

The Federal Communications Commission has assigned the call letters KTWR to the Guam transmitter site.
