The strong-lined K giant star HD 112127 exhibits an extremely strong lithium resonance line in its spectrum. In most other respects the atmosphere of the star resembles the well-studied, strong-lined star ..mu.. Leo. A model atmosphere analysis has been carried out for HD 112127 with particular emphasis on the light element abundances. Iron peak elements show essentially solar composition while the CNO group is enhanced by about 0.2 dex. The carbon isotope ratio is near 20, while the lithium content of this star is approximately the maximum seen in unevolved stars. Schemes for the production of lithium in a relatively low luminosity giant are discussed.
