Luca della Robbia (1399/1400–1482) is an Italian sculptor from Florence, noted for his glazed terracotta roundels, in a technique he apparently develops himself.

Though a leading sculptor in stone, after developing his technique in the early 1440s, he mainly produces terracotta hereafter, and passes the technique on to his nephew Andrea della Robbia and great-nephew Giovanni della Robbia.

His large workshop produces both cheaper works cast from molds in multiple versions, and more expensive one-off individually modeled pieces.

The glaze makes his creations more durable in the outdoors and thus suitable for use on the exterior of buildings.

His work is noted for its charm rather than the drama of the work of some of his contemporaries.

Two of his famous works are The Nativity, circa 1460 and Madonna and Child, circa 1475.

In stone his most famous work is also his first major commission, the choir gallery or "cantoria" in Florence Cathedral (1431–1438).

Della Robbia is praised by his compatriot Leon Battista Alberti for genius comparable to that of the sculptors Donatello and Lorenzo Ghiberti, the architect Filippo Brunelleschi, and the painter Masaccio.

By ranking him with contemporary artists of this stature, Alberti reminds us of the interest and strength of Luca's work in marble and bronze, as well as in the terra-cottas always associated with his name.
