The current status of observational studies of lithium depletion in open clusters is reviewed, concentrating mainly on G and K type stars. I attempt to answer the following questions: Can the lithium depletion patterns seen in open clusters be explained in terms of standard stellar evolution models? What is the observational evidence for non-standard mixing processes and on what timescales do they operate? Does metallicity play a significant role in lithium depletion? Can lithium still be used as a means of dating young stars? What future observations might yield better answers to these questions?
