Ficus racemosa, the cluster fig, red river fig, udumbara, audumbara, or gular (Hindi: गूलर), is a species of plant in the mulberry family Moraceae. It is native to tropical Asia and Australia. It is a fast-growing plant with large, very coarse leaves, attaining the size of a large shrub or even larger in old specimens. A distinctive feature of its growth habit is the cauliflorous nature of its fruiting, where the syconia (figs) grow in dense clusters directly from the trunk and larger branches. The ripe figs are a favourite food of the rhesus macaque, and the plant also serves as a host for the caterpillars of the two-brand crow butterfly (Euploea sylvester) of northern Australia.

The species is of cultural importance in Hinduism and Buddhism. The tree is also important to the Dusunic peoples of Sabah, Malaysia, where it is called Nunuk Ragang.
