The square-tailed drongo-cuckoo (Surniculus lugubris ) is a species of cuckoo that resembles a black drongo. It is found in Sri Lanka and Southeast Asia and is a summer visitor to the Himalayas from Kashmir to eastern Bangladesh. The calls are series of piercing sharp whistles rising in pitch but shrill and choppily delivered.

In flight a white wing-stripe is visible from below. It is a brood parasite on small babblers. It is not known how or whether the drongo-like appearance benefits this species but it is suspected that it aids in brood-parasitism just as hawk-cuckoos appear like hawks.
The square-tailed drongo-cuckoo was formerly considered conspecific with the fork-tailed drongo-cuckoo (together known as the Asian drongo-cuckoo), but vocal and morphological differences suggested that the species should be split. That treatment is followed here.
