Svetlana Kirilenko (Russian: Светла́на Кириленко) is the maternal cousin of Tony's ex-Comare Irina and is the manager of a home care nursing business. Irina has stated in the past that they have a sister-like rivalry, as Svetlana has a very committed boyfriend, an American fiance named Bill who works for the New York Mets, whereas Irina does not have a fiance or boyfriend. During her childhood, Svetlana developed an infection on her leg which was amputated soon afterwards. She was first hired as Livia Soprano's nurse since Janice had left town. When Livia dies, Tony allows Svetlana to remain at Livia's until she can get settled. However, when Janice asks the whereabouts of Livia's phonograph records, Svetlana informs Janice that Livia bequeathed the records to her. In revenge, Janice steals Svetlana's prosthetic leg. Svetlana then sends the Russian mob after Janice as a counterattack.
Svetlana resurfaces as Uncle Junior's nurse after he suffers a fall at the courthouse. One afternoon while Uncle Junior is asleep, Tony has sex with Svetlana but they are caught by Junior's nurse, Branca. Irina soon finds out about this and informs Carmela about the affair, prompting Carmela's violent confrontation of Tony and their ultimate separation.
Tony admires Svetlana for her toughness of spirit and her refusal to allow her disability and misfortune to get in the way of her ambitions. Arguably, Svetlana is the most psychologically balanced of all Tony's extramarital affairs.
