The NUS Internal Shuttle Bus (ISB) network serves the National University of Singapore (NUS)’s Kent Ridge Campus.
These shuttle buses are overseen by the Transport, Logistics and Car Park Department, under the Office of Campus Amenities (OCA). The shuttle bus service is contracted to private bus operator ComfortDelGro Bus Pte Ltd. The company owns, operates and maintains the fleet of buses, and manages the bus drivers.

During NUS’ AY2020/21 Semester 1 amid the COVID-19 pandemic, the ISB network was modified in line with NUS’ zoning strategy which minimised intermingling of students and staff across zones. Routes were amended such that each zone had a direct ISB service to Kent Ridge MRT station and other shared amenities within designated neutral zones (e.g. school accommodation, studios, sports facilities and student support facilities) subject to access restrictions.
Other Withdrawn Routes:
|UT-CLB||University Town ↔ Central Library|
|UT-FOS||University Town ↔ Faculty of Science.

- Scania K230UB (SC Auto) 12m (2010)
- Volvo B9L (SC Auto) 11m (2015)
Nearly all shuttle buses are fully-low-floor Volvo B9L buses. They bear the orange NUS livery and are fitted with a next stop announcement system.
Both the low-entry Scania K230UB and low-floor Volvo B9L buses bear orange NUS liveries and were brought in to replace older, high-floor private buses. These newer buses are built in a city bus configuration for quick boarding and alighting of passengers. In addition, many of the buses have special liveries on various themes, e.g. Graduate Club, AlmuNUS, and various faculties of the University.
