Dalmacio Langarica Lizasoain (5 December 1919 – 24 January 1985) was a Spanish professional road racing cyclist during the 1940s and 1950s and a directeur sportif in the 1970s.
At the 1948 Vuelta, Langarica tried desperately to best eventual winner Bernardo Ruiz but suffered a bad fall during the stage between A Coruña and Ourense. He ended finishing fourth overall and second in the climbers classification.
After finishing his competitive cycling career, Langarica became a directeur sportif, including serving as manager for the all-Spaniard cycling team, KAS, which included Francisco Galdós, who finished in 8th place (the highest finish of a Spaniard at the 1970 Tour de France[1]).
