Larrocha is an impact crater on Mercury. It has a diameter of 196 km (122 mi), and it is one of 110 peak ring basins on Mercury.[2] It is located in the Victoria quadrangle (H-2 quadrangle) at 43°17′N 69°50′W / 43.29°N 69.83°W / 43.29; -69.83 (Larrocha).[1]

Larrocha was named after Spanish pianist Alicia de Larrocha; this name was adopted by the International Astronomical Union (IAU) on June 18, 2013.[1]

Larrocha contains abundant hollows, including a large patch on the east side that is over 15 km long.
