Anthurium lentii is a species of flowering plant in the family Araceae, native to Colombia, Costa Rica and Panama.

[2] Leaves are 15 to 50 cm (6 to 20 in) in length; broad, ovate, glabrous, mid-green, with prominent veins.

The inflorescence is erect to spreading, with a peduncle 30–88 cm (12–35 in) long and 5–10 mm (0.2–0.4 in) in diameter.

Flowers are contained in tight spirals on a spadix which is elongated into a spike shape.
