Rosemary Lassig (10 August 1941 – 1 November 2017), known after marriage as Rosemary Lluka, was an Australian breaststroke swimmer of the 1960s, who won a silver medal in the 4×100-metre medley relay at the 1960 Summer Olympics in Rome. Lassig combined with Dawn Fraser, Jan Andrew and Marilyn Wilson to register a silver medal in the 4×100-metre medley relay five seconds behind the winners, the United States. In her only individual event, the 200-metre breaststroke, she did not advance beyond the preliminary heats.

Lassig, who was born in Bundaberg, Queensland, died in Sydney on 1 November 2017 due to complications caused by Alzheimer's disease.{{cite web|title=Olympic legends pay tribute to Bundaberg's finest Rosemary Lassig|url=https://www.swimming.org.au/NewsCentral/Olympic-legends-pay-tribute-to-Bundaberg%E2%80%99s-finest.aspx|website=Swimming Australia|accessdate=15 November 2017}}{{Cite news|url=https://www.news-mail.com.au/news/bundaberg-olympian-was-a-trail-blazer/3262388/|title=Bundaberg Olympian was a trail blazer|work=News Mail|access-date=20 August 2018|language=en}}
