Colégio Sion, Private Catholic school in Higienópolis, São Paulo, Brazil.

Colégio Sion is a private Catholic school in the Higienópolis neighborhood of São Paulo housed in a three-story building with gardens, laboratories, and sports facilities. The campus also features a spacious self-service dining area for students.

The Congregation of Nossa Senhora de Sion founded the school in 1901 following an invitation from the Brazilian government to improve education in the country. This establishment was part of a broader effort to bring quality schooling to São Paulo.

The school's name comes from the Congregation of Our Lady of Sion, founded in France in 1843 by the brothers Théodore and Alphonse Ratisbonne. Founded in São Paulo in 1901, it was long a French-model boarding school for wealthy girls, teaching etiquette and trousseau standards; it is now coeducational and more secular in content while still presenting itself as Christian.

The school is located at Avenida Higienópolis 983 in a central neighborhood with good public transportation access. Visitors should know that the property is a private facility and accessible only with prior permission.

The site at Avenida Higienópolis 983 housed the "Sanatorio Inglez" in 1870 and later the Hotel Higienópolis before the sisters bought it. The original structure was much smaller; the present buildings result from later expansions. The 1940s renovations and the eclectic Ramos de Azevedo project were listed by Condephaat after a campaign led by former students.
