The Information Telegraph Agency of Russia (Russian: Информационное телеграфное агентство России, Informatsionnoye telegrafnoye agentstvo Rossii), abbr. ITAR-TASS (Russian: ИТАР-ТАСС), is a major news agency in Russia, founded in 1902.

Headquartered in Moscow, the agency has 74 offices in Russia and CIS, as well as 65 bureaus around the world.

Its origin dates back to December 1902 when it began as the Commercial Telegraph Agency under the Ministry of Finance, with Torgovo-Promyshlennaya Gazeta's staff being the main supplier of journalists. As the demand for non-business began during the first battles of the Russo-Japanese War in February 1904, the agency had to change its name to the St. Petersburg Telegraph Agency (SPTA). As there was no change of headquarters and almost no change in its staff and function, it was a mere rebranding. In August 1914, one day after St. Petersburg was renamed Petrograd, SPTA was renamed the Petrograd Telegraph Agency (PTA). It was seized by Bolsheviks in November 1917and by December was re-named as the Central Information Agency of the Soviet Russian Council of People's Commissars'.
