Katya Kinski is a fictional character from the Australian soap opera Neighbours, played by Dichen Lachman. She made her first on-screen appearance during the episode broadcast on 12 December 2005. Lachman originally auditioned for the role of Elle Robinson. But producers asked her to play Katya instead. Katya is characterised as a "bitchy nasty person" with a "dark past". She arrives in Erinsborough to visit her terminally-ill father Alex before he died. She reunites with her younger siblings Rachel and Zeke Kinski. Katya feuds with Susan Kennedy and Karl Kennedy over custody of her siblings. Lachman believed that her flawed character disliked Susan to justify her own failings as a sister.
