Magna Roma, or 892-IV, was a Class M world located in the 892 star system. The planet was orbited by two moons and was home to a humanoid race which developed a culture very similar to that of Earth's Roman Empire. (ST reference: The Worlds of the Federation)

In 2260, the SS Beagle received a meteorite impact and was damaged, leading to a crash on 892-IV. (Last Unicorn RPG module: All Our Yesterdays: The Time Travel Sourcebook)

Magna Roma was later cited as an example of Hodgkin's Law of Parallel Planetary Development as it developed a parallel Empire. (TOS episode: "Bread and Circuses") It was later theorized that the planet was populated by the descendants of Earth Romans that were placed on Magna Roma by the Preservers. (TOS novel: Ex Machina)
