"Telchis" is also the singular form of "Telchines".

In Greek mythology, Telchis (Ancient Greek: Τελχίς means "one of the Telchines") may refer to two different or the same characters:

• Telchis or Telchin, the third king of Sicyon who reigned for 20 years.^[1] He was the son and successor of Europs, thus grandson of the primeval king Aegialeus. Telchis' heir was his own son Apis to whom was subsequently born Thelxion.^[2]

• Telchis, an Argive companion of Thelxion. The two are said to have deposed and killed the Argive Apis, son of Phoroneus and Teledice, who had left no offspring.^[3] Apis' death was later avenged on them by Argus Panoptes.^[4]
