St. Joseph's College, the first school taken over by the La Salle Brothers in Hong Kong, has a long history. In 1875, six La Salle Brothers took over St. Saviour's College, which was founded in 1860, and renamed it as St. Joseph's College. It was really the first all boys Catholic school in Hong Kong.

In 1876, the College expanded and moved from its original premises in Pottinger Street to a larger one at 9, Caine Road, known as Buxley Lodge. Five years later, a lack of space again resulted in the College being moved to Glenearly below Robinson Road. Then in 1918, an earthqake caused severe damage to the premises and the school had to move again to the present site - 7 Kennedy Road, formerly known as the Club Germania (the German Club).

Now, the building where the F.1-4 classes are situated was erected in 1920; at that time the number of students was about 650. In chapel block was completed and in 1963 the block on Kennedy Road was replaced by the present building. The new building was opened by Sir Robert Black, the then Governor of Hong Kong. In 1968, in order to admit more students, the primary section was transferred to an independent establishment at 48 Wood Road, Wanchai. In 197 St. Joseph's College Kindergarten was established on the top floor of the Primary School Building.

After years growth, St. Joseph's College now provides education for about 1,300 students. The College has produced highly capable and versatile students, and many of them play a prominent part in Hong Kong life today. Besides it fine academic record, the College is well known for its football and sport achievements.

The College badge is very beautiful and its motto reads "Labore et Virtute" - Diligence and Virtue - which reminds its students that it is by hard work and virtue that they will make a success of their lives.
