thumb|Several ribosomes synthesizing a polypeptide on the same mRNA strand A polysome (or polyribosome or ergosome) is a group of ribosomes bound to an mRNA molecule like "beads" on a "thread". It consists of a complex of an mRNA molecule and two or more ribosomes that act to translate mRNA instructions into polypeptides. Originally coined "ergosomes" in 1963, they were further characterized by Jonathan Warner, Paul M. Knopf, and Alex Rich.

多核糖体（polyribosome，或簡稱為 polysome），又稱聚核糖體、多聚核糖體，是一束或一组核糖体。这些核糖体可以附着在mRNA上，同时进行轉譯，使得蛋白质的轉譯速度大大加快。 这一现象最早由 Jonathan Warner, Paul Knopf 和 亚历山大·里奇于1963年发现。
