Sandford Park School is an independent, non-denominational, co-educational secondary school, located in Ranelagh, Dublin, Ireland.

The school was founded in 1922 by Alfred Le Peton, who served as its first headmaster.

Le Peton had previously served as joint headmaster of Earlsfort House School alongside Ernest Exshaw.
