The rotation periods of low mass stars are known to evolve coherently as a function of stellar mass and age. On the main sequence, stellar winds are the principle agent of angular momentum loss. The rate at which a star loses angular momentum depends strongly on the strength and geometry of its magnetic field. In this talk, I will discuss the current state of knowledge of stellar magnetic fields and their effect on rotation period evolution.
