Girolamo Amati (1561–1630) was an Italian luthier, active from 1580 to 1630.

This article relies largely or entirely on a single source. (July 2023)

Born in Cremona, Girolamo was the youngest son of Andrea Amati and brother of Antonio Amati. Girolamo worked, probably from 1575, with his brother, in his father's workshop. With the latter, he refined his construction technique and style. For about ten years, they co-signed their works with their Latinized names: "Antonius & Hieronymus Amati".

Girolamo slightly increased the size of his instruments, compared to those of his father.

His son, Nicolò Amati (1596-1684), whom he trained in the workshop, was the master of Andrea Guarneri and possibly of Antonio Stradivari and Francesco Rugeri.^[1]
