Encephalartos sclavoi, common name Sclavo's cycad, is a critically endangered[1] cycad in the family Zamiaceae.

It is endemic to Tanzania, with a population of only ~50 mature plants.

[3] Encephalartos sclavoi grows to about 1 metre (3.3 ft) high.

The leaves are 170 to 200 centimetres (5.6 to 6.6 ft) long, dark green and semiglossy.

It was described in 1990 by Aldo Moretti, D.W. Stevenson and Paolo Deluca, honoring Jean Pierre Sclavo, a French collector of cycads, who first discovered this species.
