St. Francis' Institution is a public all-boys school in Malacca, Malaysia with La Sallian tradition.

The School Badge is an emblem that incorporates a star, an armorial bearing, the Famosa Gate, and an open book, to show respectively the School's association with the De La Salle Order; its connection with its patron, St. Francis Xavier; its location in the most historic town in Malaysia; and its purpose which is education.

This heraldic device of horizontal divisions and crescent was the coat-of-arms of the Castle of Xavier, the ancestral home of St. Francis.

In the last quarter is an open book, yellowish green in colour on a black background, and showing the words ‘Initium Sapientiae’ meaning ‘The beginning of wisdom’.

Beneath the shield is the motto ‘Age Quod Agis’ which is the best translated as ‘Whatever You Do, Do It Well’.
