Teïspes (from Greek Τεΐσπης, Teispēs; in Old Persian: 𐎨𐎡𐏁𐎱𐎡𐏁[2] Čišpiš; Akkadian: 𒅆𒅖𒉿𒅖 Šîšpîš,[3] Elamite: Zi-iš-pi-iš)[4] ruled Anshan in 675–640 BC.

According to 7th-century BC documents, Teispes captured the Elamite city of Anshan, speculated to have occurred after the Persians were freed from Median supremacy, and expanded his small kingdom.

[4] The Old Persian version of the name is Čišpiš; Walther Hinz and Heidemarie Koch interpret it as *Čaišpiš, but this appears to be incorrect.

[5] Another Iranian derivation proposed by Wojciech Skalmowski is that the name is a compound related to Old Indian cit-, "thought, intelligence", and pi-, "to swell, overflow".

[5] The verb stem piš-, meaning "to renew, restore", is indeed found in some Elamite names, but the first part is hard to explain.
