Psittacanthus cucullaris is a species of mistletoe in the family Loranthaceae, and is native to Costa Rica, Bolivia, Colombia, Ecuador, French Guiana, Peru, Suriname, Venezuela and Brazil.

The flowers occur in sessile triads, with a main and secondary peduncle of the inflorescence which is 1–2 cm long.

The fruits are ovoid and 10–15 mm long by 9–12 mm wide, and are green when immature and black or purple when ripe and their base is encircled by the pink, orange or red subfloral dome.

[4] It is easily recognized by the spiky leaves, the terminal and axillary inflorescences at the apex of the branches, the bracts that subtend the triads with sessile flowers, the revolute subfloral domes that surround the caliculum and the base of the flowers, which persist in the fruit.

[4] In Brazil, it grows in the Amazon rainforest, the Central Brazilian savanna, and the Pantanal.
