Telkom-1 is an Indonesian geostationary communications satellite operated by PT Telkomunikasi.

Lockheed Martin Commercial Space Systems built the satellite for PT Telkomunikasi (TELKOM) of Indonesia to link the nation's thousands of different islands and archipelagos. The TELKOM-1 satellite replaced the existing Palapa B2R satellite which was retired later that year. TELKOM selected the A2100A to meet the growing requirements for telecommunications services. The company projects the annual increase in Indonesia's demand for services will be approximately 1.5 million telephone line units per year.

TELKOM-1 supported a variety of telecommunication applications, including high-speed digital traffic compatible with Very Small Aperture Terminal applications, which allows very small satellite dishes to receive signals, eliminating the need for expensive, fixed-site satellite dishes. The satellite's payload was built at the Lockheed Martin Commercial Space Systems facilities in Newtown, PA., and is configured with 24 C-Band and 12 extended C-Band transponders.
