MTD ( Swedish abbreviation for Mobiltelefonisystem D, or Mobile telephony system D) was a manual mobile phone system for the 450 MHz frequency band. It was introduced in 1971 in Sweden, and lasted until 1987, when it was made obsolete by the NMT automatic service. The MTD network had 20,000 users at its peak, with 700 people employed as phone operators.

MTD was also implemented in Denmark and in Norway (from 1976), which allowed roaming within the Scandinavian countries.
