Intercalation may refer to:
- The insertion of a leap day, week or month into some calendar years to make the calendar follow the seasons.
- Chemistry, where intercalation is the insertion of a molecule (or group) between two other molecules (or groups). For example, 2,4 dichlorophenoxyacetic acid or 2-(2,4 dichlorophenoxy-)propionic acid intercalates between layers of clays.
- Biology, where intercalation refers to how certain drugs and mutagents bind to DNA. This type of intercalation was discovred by Leonard Lerman.
- University administration, where intercalation is the period when a student is officially suspended from studying for an academic degree.
