Tercera División (English: Third Division) was the fourth tier of the Spanish football league system. Until 1977, it was the third tier of the Spanish football league system. Founded in 1929, it was below the Primera División (also known as La Liga), the Segunda División, and the semi-professional Segunda División B.
For the 2021–22 season, Tercera División was replaced by Tercera División RFEF, which became the fifth tier due to the creation of a new, semi-professional third division by the Spanish federation (RFEF) called the Primera División RFEF.
