Luigi Pichler (January 31, 1773 in Rome – March 13, 1854 in Rome) was a German-Italian artist in engraved gems.

Son of Anton Pichler and half-brother and student of Giovanni Pichler, Luigi was an apprentice to his greatly renowned 39-year older brother and painter Domenico de Angelis.^[1] He travelled to Vienna, where he, in 1818, was made professor of gem-engraving at the Vienna Academy of Fine Arts,^[1] and where he, working for Francis I, created replicas of some of the most famous gems in Austria as part of the Vienna Cabinet,^[2] a gift for Pope Pius VII. His works are almost exclusively intaglio, and he created many copies of his brother's and father's work.^[2] In 1850 he turned back to Rome, where he died in 1854.

His works include a head of Ajax, the gods Apollo, Mars, Venus, Cupid, and Psyche, a head of Julius Cæsar; as well as two heads of Jesus.^[2]
