Alberto di Giovanni Alberti, or Berto di San Sepolcro (1525–1599) was a Tuscan architect, wood carver and painter.
Alberti was born at Sansepolcro. He was engaged as master carver at Arezzo, where he was responsible for the choir stalls in the Cathedral, and at Rome (from 1564 to 1586). As a wood carver he specialized in wood inlay, or intaglio.
At Città di Castello he executed carvings in a number of churches.
His sons were Alessandro Alberti (1551-1596), a painter; Cherubino Alberti (1553-1615), an engraver in Rome; and Giovanni Alberti (1558-1601).
Two of Alberti's diaries survive. They contain detailed information on commissions, designs, and other drawings. They also give details on his children.
