Poco Lena (1949–1968) was an outstanding cutting mare, and dam of two famous Quarter horse cutting horses and stallions: Doc O'Lena and Dry Doc.^[1]

Poco Lena was foaled in 1949, the daughter of Poco Bueno out of a daughter of Pretty Boy named Sheilwin. She traced to Peter McCue on both her sire's and her dam's side.^[2]

With the American Quarter Horse Association (or AQHA) Poco Lena earned her AQHA Championship, a Performance Register of Merit, a Superior Cutting Horse award and a Superior Halter Horse award.^[3] She was also the AQHA High Point Cutting Horse in 1959, 1960, and 1961.^[3] With the National Cutting Horse Association (or NCHA) she earned a total of $99,819.61 in cutting contests in her career.^[4] She earned a Certificate of Ability, as well as a Bronze and a Silver Award with the NCHA.^[5] She was also inducted into the NCHA Horse Hall of Fame.^[6]

In late 1961, Poco Lena foundered. She recovered, and was showing well when in October 1962 her owner, B. A. Skipper Jr., died in a plane crash. In the confusion, Poco Lena was left in a trailer for four days without food or water. She foundered again, and never competed again.^[1] Eventually she was bought by the owners of Doc Bar, Dr. and Mrs. Stephen Jensen. After much nursing and effort, Poco Lena produced two foals when bred to Doc Bar – Doc O'Lena and Dry Doc, both of whom won the NCHA Cutting Futurity.^[1] However, Poco Lena's founder deteriorated after the birth of Dry Doc, and on December 16, 1968, she was euthanized.^[1]

Poco Lena was inducted into the AQHA Hall of Fame.^[7]
