Kampong Mulaut is a village in Brunei-Muara District, Brunei, about 14 kilometres (8.7 mi) from the capital Bandar Seri Begawan.

According to one of the residents of Kampong Mulaut, the earliest school built there was Sekolah Rendah Orang Kaya Setia Bakti.

When the Kampong Mulaut area was newly developed with the construction of roads and schools, when a person stood on the hill there and looked towards the flat area below, the person looked as if the flat area under the hill was covered by the sea.

Based on the scenery, it was the inspiration to name this village as Kampong Mulaut.

In terms of the private enterprise aspect, Kampong Mulaut is host to several small and retail businesses such as cracker making and sugarcane cultivation (gelagah).
