The Cambridge Astronomical Survey Unit (CASU) is part of the Institute of Astronomy, Cambridge University and is mainly involved in survey astronomy.

Expertise within the group covers a broad range of ground-based and space-based projects ranging from data processing and image analysis techniques through to data curation and access to UK facility data archives. Modern era wide-field digital surveys produce vast amounts of data and CASU is at the forefront of automatically processing and archiving these legacy products.

Research interests of individual CASU members include: statistical analysis techniques for data mining; searches for rare objects in large area surveys; properties of nearby galaxies and star clusters; attitude control and exploitation of astrometric space missions.
