Ricardo Castro Herrera (Rafael de la Santísima Trinidad Castro Herrera) (7 February 1864 – 27 November 1907) was a Mexican concert pianist and composer, considered the last romantic of the time of Porfirio Díaz.
Castro began his musical career as a concert pianist and composer before finishing his studies. In 1882, he won two prizes. At 19, Castro finished his First Symphony in C Minor; the symphony was premiered in 1988, 81 years after his death.
In 1883 the Government of Mexico chose some of Castro's works to send to Venezuela for the Simon Bolivar centenary and later in 1884 he made a concert tour through United States.
