Aristokles (Ἀριστοκλῆς), a Greek sculptor, working in Attica at the end of the 6th century BC.
A grave stele of Pentelic marble, dated to around 510 BC, and found in 1838 in the ancient cemetery of Velanideza, eastern Attica, is signed at the bottom "work of Aristokles" (ἔργον Ἀριστοκλέος, ergon Aristokleos). The rectangular base of the stele is also inscribed with the name of the deceased man Aristion (Ἀριστίονος, Aristionos). 
The stele itself has a finely sculpted and painted low relief showing the full-length figure of a bearded, barefooted hoplite wearing a helmet, a cuirass over a chitoniskos and greaves (shin armour), and holding a spear in his left hand. The background was painted red, and some of the colour can still be seen, as well as traces of red, blue and yellow on the figure. The tip of the beard as well as the top of stele, including the top of the helmet and the finial, are missing.
Stele height 202 cm, width 14 cm.
Base height 24 cm, width 72 cm, depth 43 cm.

A plaster cast of the stele, without the base, is on display in the Ashmolean Museum, Oxford. Inv. No. D4.
The lower part of a similar Attic grave stele, made of Hymettian marble and dated to 525–515 BC, shows the legs and feet of a hoplite and the lower part of spear. In the panel below the figure is a painted relief of an armoured warrior mounting a four-horse chariot, probably a competitor in an apobates race
