Methodist Boys' School, Kuala Lumpur is a semi-government aided Cluster School of Excellence and High Performance School in Kuala Lumpur, Malaysia. It was founded in July 1897, making it one of the oldest schools in Malaysia. It is known as MBS and its students are known as MBSians. The school is also known as Horley School, a reference to one of its principals, Rev. William E. Horley, who was responsible for changing and giving the school its present name from the previous name of Anglo-Tamil School. The name Horley School has been widely misunderstood as a reference to marble, which is also called Horley in Chinese, a game that was popular amongst its students then. It is noted for its library, which attracts visits from many other schools.
