Luca della Robbia (, also , ; 1399/1400–1482) was an Italian sculptor from Florence. Della Robbia is noted for his colorful, tin-glazed terracotta statuary, a technique which he invented and passed on to his nephew Andrea della Robbia and great-nephews Giovanni della Robbia and Girolamo della Robbia. Though a leading sculptor in stone, he worked primarily in terracotta after developing his technique in the early 1440s. His large workshop produced both cheaper works cast from molds in multiple versions, and more expensive one-off individually modeled pieces.
