Otenet was a major internet service provider of Greece established in 1995.

Otenet S.A. was an S.A. (corporation) providing Internet products and services.

The other share holders were NCSR Demokritos (Ariadnet) and National Technical University of Athens each holding 10,000 shares.

OTE eventually bought back the shares from these organizations in 2006.

Especially the poor performance of their networks on Greece's many small islands has drawn considerable criticism.
