Katy Ellen French (31 October 1983 – 6 December 2007) was an Irish socialite, model, writer, television personality and charity worker.

While still in school she worked part-time as a hostess at the Dublin branch of the Planet Hollywood restaurant chain.

Katy French studied psychology and marketing before working for the Assets Modelling Agency and later writing articles for several Dublin magazines and newspapers.

[4] She represented Sony Ericsson and Suzuki among many other brands, becoming more famous in 2007 as a result of her fiancé, restaurateur Marcus Sweeney, ending their relationship in a very public fashion after French was photographed for a lingerie shoot for the Sunday Independent in his restaurant in January of that year.

[4] She worked for several Irish charities including Our Lady's Children's Hospital, Crumlin and GOAL in Calcutta, India.

"[16] In 2010 two people were charged with supplying cocaine to Katy French and in failing to get medical assistance in a timely fashion.

Trim Circuit Court was told that a second charge against the pair was not being pursued, that they had intentionally or recklessly engaged in behaviour relating to the supply of cocaine to French and failed to get medical assistance in a timely fashion.
