A corda dorsal, notocorda ou notocórdio (do grego notos: dorso, costas + latim chorda: corda), é uma estrutura celular, semelhante a um bastão fino, que se forma durante o desenvolvimento embrionário e está presente, pelo menos em uma fase da vida, em todos os cordados.
The chordates are named for the notochord, which is a flexible, rod-shaped structure that is found in the embryonic stage of all chordates and in the adult stage of some chordate species. It is located between the digestive tube and the nerve cord, and provides skeletal support through the length of the body.
