Rosemary Smith (born 7 August 1937) is a rally driver from Dublin, Ireland. She initially trained as a dress designer.
Smith entered her first rally as a co-driver. After deciding that navigating was not to her liking, she switched to driving. She came to the attention of the Rootes Group's Competition Department, which offered her a works drive. In 1964, she took the ladies' prize on the Circuit of Ireland Rally driving a Sunbeam Rapier. The following year she won the Tulip Rally outright in a Hillman Imp.
Smith was controversially disqualified from the 1966 Monte Carlo Rally after winning the Coupe des Dames, the ladies' class. Ten cars in total were disqualified. Rosemary Smith said she would never compete again unless the decision were reversed.
Her other competition successes included an outright win in the 1969 Cork 20 Rally. Smith has won the ladies' prize several times on the Scottish Rally and on the Circuit of Ireland Rally, twice each on the Alpine Rally and on the Canadian Shell 4000 and once on the Acropolis Rally. She also has numerous class wins to her name.
In 1966, Smith appeared as a guest on an episode of What's My Line. Arlene Francis, Mark Goodson, Ginger Rogers, and Bennett Cerf were on the panel and successfully guessed her "line" as a race car driver.
On 10 May 2017, Smith did a test drive with the show car of Renault F1 on the Circuit Paul Ricard as part of a filming day. This made her the oldest person to drive a 800bhp race car
