Ludovika Antje Margareta Jakobsson-Eilers (née Eilers, 25 July 1884 – 1 November 1968) was a German-Finnish figure skater. Competing in pair skating with skating partner and husband Walter Jakobsson, she won the gold medal at the 1920 Summer Olympics, where she was the only German-born athlete. The pair also earned three world titles, in 1911, 1914 and 1923, and finished second and fifth at the 1924 and 1928 Olympics, respectively. Eilers was also successful in single skating, winning a bronze medal at the 1911 World Championships.
Eilers met Jakobsson in 1907 while he was studying engineering in Berlin. They started to compete together in 1910 and married in 1911; hence the International Skating Union counts their 1910–1911 medals as half-German, half-Finnish, and those after 1911 as Finnish. The couple lived in Berlin until 1916, when they moved to Helsinki. There Walter got a job of technical director with Konecranes, a leading manufacturer of cranes, while Ludovika starred in a few Finnish silent films.
