The Mussau triller (Lalage conjuncta) is a smaller member of the cuckooshrike family, Campephagidae.

It was formerly considered a subspecies of the varied triller.

It is found on the St Matthias Islands in the Bismarck Archipelago.

Photographed and sound-recorded for the first time in 2024[1], the species is now thought to be restricted to the centre of the island and may be at risk due to logging.
