Aristokles (Ἀριστοκλε͂ς or Ἀριστοκλῆς), a Greek sculptor, working in Attica at the end of the 6th century BC. Nothing is known about his life, and only his name is known from signatures on surviving parts of funerary monuments from Attica. These may be have been works by more than one sculptor of this name.
Works by one or more sculptors of the same name and thought to have been working in the 6th - 5th centuries BC are mentioned by ancient authors. One is known as Aristokles of Kydonia (also referred to as Aristokles the Elder, perhaps around 600-568 BC) and the other Aristokles of Sikyon (Aristokles the Younger), who may have been the grandson of the former and was mentioned by Pausanias as the brother of Kanachos of Sikyon
(the Elder), thought to have been working around the same time (around 540-508 BC).
"Ptolichus was a pupil of his father Synnoon, and he of Aristocles the Sicyonian, a brother of Canachus and almost as famous an artist."

Aristokles was not an uncommon name, and no connection has been established between these artists and the sculptor (or sculptors) working in Athens around this time.
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.
National Archaeological Museum, Athens. Inv. No. 29.
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
Metropolitan Museum of Art, New York. Inv. No. 38.11.13.
