A centriole is a tiny, cylindrical structure found in most animal cells that is made up of nine groups of three microtubules arranged in a ring pattern. Centrioles help organize the cell's internal skeleton and play an important role in dividing cells by helping to position the machinery that pulls apart chromosomes during cell division.

In cell biology a centriole is a cylindrical organelle composed mainly of a protein called tubulin. Centrioles are found in most eukaryotic cells, but are not present in conifers (Pinophyta), flowering plants (angiosperms) and most fungi, and are only present in the male gametes of charophytes, bryophytes, seedless vascular plants, cycads, and Ginkgo. A bound pair of centrioles, surrounded by a highly ordered mass of dense material, called the pericentriolar material (PCM), makes up a structure called a centrosome.
