Vodka (ウオッカ; 4 April 2004 – 1 April 2019) was a Japanese Thoroughbred racemare which won the 2007 Group One (GI) Tokyo Yūshun (Japanese Derby), the first filly to win this race in 64 years, as well as the 2009 Japan Cup. She won seven G1 races in Japan and was the highest earning racemare in Thoroughbred history at the time.

Vodka was foaled on 4 April 2004 at Country Bokujo in Shizunai, Hokkaido. She was a bay mare by the 2002 Tokyo Yushun (Derby) winner, Tanino Gimlet out of Tanino Sister by Rousillon (USA).

Vodka was owned by Yuzo Tanimizu and trained by Katsuhiko Sumii.

In 2006, Vodka won her first race start and was second in the ungraded Kigiku Sho race which was also contested at the Kyoto Racecourse before she won the G1 Hanshin Juvenile Fillies race at the Hanshin Racecourse, beating out Aston Machan by a neck. Vodka was then awarded the 2006 JRA Award for Best Two-Year-Old Filly.

In 2007, Vodka won her first start in the ungraded Elfin Stakes, followed by another win in the G3 Tulip Sho, from Daiwa Scarlet, who finished in second place. At her next start on 8 April, in the G1 Oka Sho (Cherry Blossom Awards), the first race of the Japanese Filly Triple Crown, Daiwa Scarlet relegated Vodka to second place. Daiwa Scarlet and Vodka would go on to meet a total of four times that year. Daiwa Scarlet bested her in three of those races. One of those contests was not a win for Daiwa Scarlet though, in the 2007 G1 Arima Kinen at Nakayama Racecourse, Daiwa Scarlet finished second to Matsurida Gogh, with Vodka finishing 11th.

Vodka's next race start was in the G1 Tokyo Yūshun, also known as the Japanese Derby, the second jewel in the Japanese Triple Crown. Fillies are usually entered in the Yushun Himba, also known as the Japanese Oaks, which is the second jewel of the Japanese Filly Triple Crown which is a week before the race, however, in a move that shocked the racing world, Vodka won handily, defeating a field of some of the best three-year-old colts in the country. She became the first filly to win the race in 64 years.

Vodka was unplaced in her next start before racing in the G1 Shuka Sho, which is the last race of the Japanese Filly Triple Crown races. Daiwa Scarlet won the race, with Vodka finishing in third place. She was entered in the 2007 Queen Elizabeth II Commemorative Cup, but was scratched a few hours before the race due to what was thought to be a hip problem. In her next start Vodka finished 4th in the G1 Japan Cup. Vodka subsequently did not place in her last start of the season.

Despite winning the Japanese Derby. She lost to Daiwa Scarlet in Japanese Champion Three Year old Filly, as Vodka never finished above her in the 3 races in which both horses participated, but the achievement in the Derby led to her receiving the JRA Special award (an award given to horses/person achieved special achievements, usually historical records, not awarded every year). Her 9 race starts of the season resulted in 3 wins, 1 second and 1 third place.
