OJSC Svyazinvest (Russian: ОАО Связьинвест) was Russia's largest telecommunications holding company.

Based in Moscow, it was founded according to Order №1297 of the Russian government on November 25, 1994, and was registered on September 18, 1995.

Its operation including brand and subsidiaries were fully incorporated to Rostelecom, the former long-distance telephony monopoly.

Svyazinvest's charter capital was formed by consolidating state-owned stakes in 85 joint stock telecommunications companies.
