Katya Sarah Kinski was a fictional character in the Network Ten soap opera Neighbours, and is played by Dichen Lachman. She entered the show's canvas in late 2005, when her father Alex was in the last stages of Angioimmunoblastic T-Cell Lymphoma, an acute idiopathic form of leukaemia. Katya left the show in February 2007.
After Alex died, Zeke was mute, and Susan decided to take him to Dr. Karl Kennedy (Alan Fletcher), her former husband. When Katya learned of the past relationship between Susan and Karl, her reaction wasn't one of understanding.
Soon after this, Katya initiated court proceedings so she could have custody of Rachel and Zeke, but Susan soon gave up the children to Katya. They moved out of Susan's home, but It wasn't long before she realise both she and the kids need a mother, so she and Susan made peace and she moved back in with Susan, eventually they became friends.
Katya dated Robert Robinson (Adam Hunter), under the impression that he was his twin brother, Cameron Robinson (also played by Hunter) and was heartbroken upon learning of his deception. Robert was planning on pushing Katya off a cliff, but she ended up falling off. Robert saved her life by pulling her up. She fell deeply for him until he framed his comatose brother for his crimes, and Robert returned to being himself while his innocent brother was sent to jail. Believing Cameron innocent, she, Izzy (Natalie Bassingthwaighte) and Gail (Fiona Corke) chased after him and Paul (Stefan Dennis) on a camping trip, outing Robert and saving Paul.
But she was kidnapped by him later on, and after trying to fool him into being on her side, she was found by Toadie Rebecchi (Ryan Moloney) and Susan tied up in a camper van after she hung her jumper out of the window.
Ned Parker (Daniel O'Connor) began to grow close to Carmella Cammeniti (Natalie Blair), they became more than friends and she told him they were spending too much time together and wanted time out. He then grew close to Katya, but when Carmella found out, she and Katya began to fight over Ned, with Katya pulling out all the stops. Eventually, Katya won. However Guy (Fletcher Humphrys) visited Erinsborough unannounced and blackmailed Katya into giving him money so that her secrets remained untold, and to do this she had to return to her previous habit of stealing cars. She attacked Ned, who attempted to stop her one night, but he was not aware that the person was Katya until after she was admitted to hospital later. Katya took Guy to the woods under false pretences; Guy was led to believe that he was going to be paid the money that he harassed Katya for, but she instead took a gun from her handbag. In a struggle, Katya was accidentally shot. Guy left her and took the bag Katya was carrying, which he later discovered had green paper and few real banknotes in it.
Katya was later found and taken to Erinsborough Hospital in a coma, and remained in a low response state. Guy got to know the Kinskis, but was also searching for the money and waiting for Katya to regain consciousness so that she could tell him where it was. He made frequent visits to Katya in hospital, and she often moved her eyelids or her hand when he spoke to her. She remained in a low response state until two weeks later, when Guy prepared to shock her with a defibrillator to "encourage" her to fully regain consciousness. He was stopped by Zeke, and Katya then rose up and shocked Guy with the paddle still mounted to the unit.
Katya was sent to prison, but released on bail in time to spend Christmas with her family. However, Guy showed up with a gun and took Katya, Toadie, Steph (Carla Bonner), Charlie (Aaron Aulsebrook-Walker) and Zeke hostage. During an intense struggle between Guy and Toadie, Toadie was shot.
Katya left Ramsay Street in February 2007, after receiving a suspended sentence for her crimes. She accepted the position as a medic to the Adelaide Crows football team, and left to start over in Adelaide. It has since been revealed that she is dating Paul McClain, a former Ramsay Street resident who left to take up a career in football with the Adelaide Crows.
