Colégio de Santa Inês, Catholic education institution in Luz, São Paulo, Brazil.

The Colégio de Santa Inês is a Catholic school in Bom Retiro, São Paulo, founded in 1907. Its U-shaped building, designed by Italian Salesian architect Domenico Delpiano, occupies a whole block and has an inner courtyard surrounded by columns, with an Art Nouveau facade on Rua Três Rios featuring a wooden and glass main door beneath the school's name.

The Daughters of Mary Help of Christians bought part of the Chácara Dulley on 7 July 1905 for São Paulo's first Salesian school for girls. The mothers arrived in Bom Retiro on 21 January 1907, the feast of Saint Agnes, which gave the school its name. The building, first completed in 1907, was structurally renovated in 1916. From 1918 it added secondary and teacher-training courses, the city's first private one, and began admitting boys.

The school's name changed to Colégio de Santa Inês when the nuns arrived in Bom Retiro on 21 January 1907, the feast day of Saint Agnes; Nossa Senhora Auxiliadora remains its symbol. Sunday oratório festivo, a Salesian practice, brought children into religious teaching through games and non-formal activities. The dormitories still house the Salesian nuns.

The school is located in the Luz neighborhood, which is easily accessible by public transportation and sits in a busy area of the city. Visitors should note that as an active educational facility, access and visiting hours are limited.

The land on Rua Três Rios once belonged to a chácara of the Dulley family; the Englishman Charles D. Dulley's sons founded São Paulo's first sports club there, today's Clube Atlético Paulistano, before the Salesian sisters bought the plot on 7 July 1905.
