A doctor's logbook is a record-keeping tool used by medical professionals, typically junior doctors or medical students, to document their clinical activities and learning experiences during their training or education.

A doctor's logbook may include details such as the number of hours worked, the number and types of patient cases seen, and the procedures and treatments administered. It can also include reflections on the medical cases encountered, personal feedback, and assessments of the doctor's performance from supervisors or mentors.

The purpose of a doctor's logbook is to help medical professionals track their progress and learning, demonstrate their competence and capabilities, and to guide their development towards becoming proficient in their chosen field.
