Ekspress-AM4R (Russian: Экспресс-АМ4Р meaning Express-AM4R)  was a Russian communications satellite intended for operation by the Russian Satellite Communications Company (RSCC). Constructed as a replacement for Ekspress AM4, which was left unusable after the upper stage of the launch vehicle carrying it malfunctioned, Ekspress-AM4R was also lost due to a launch failure.
Astrium, which had become part of Airbus Defence and Space by the time of the satellite's launch, constructed Ekspress AM4R, which was based on the Eurostar 3000 satellite bus. It was identical in design to Ekspress-AM4, with a mass of 5,775 kg (12,732 lb) and a planned operational lifespan of fifteen years. The satellite carried sixty-three transponders: thirty operating in the C-band of the electromagnetic spectrum, twenty eight in the Ku-band, two in the Ka-band and three in the L-band. It was to have been the largest and most powerful satellite in the Ekspress constellation.
Khrunichev was contracted to launch Ekspress AM4R, using a Proton-M / Briz-M launch vehicle - the same configuration that had failed to deploy Ekspress AM4. The launch took place from Site 200/39 at the Baikonur Cosmodrome, at 21:42:00 UTC on 15 May 2014. Shortly after launch the rocket was reported to have encountered a problem during third stage flight, and as a result the satellite failed to reach orbit.
