A meiocyte is a type of cell that differentiates into a gamete through the process of meiosis. Through meiosis, the diploid meiocyte divides into four genetically different haploid gametes. The control of the meiocyte through the meiotic cell cycle varies between different groups of organisms.

The time of initiation and the extent to which the meiocyte shows polarization by an unequal distribution of organelles in its cytoplasm, and may vary in different species.
