Endolymph is a one of two type of cochlear fluids, the other being perilymph. It is located in the scala media of the cochlea.

It is secreted by the stria vascularis (colloquially called 'battery of the cochlea') on the outer wall of the scala media.

It has a high level of potassium (K+) and generates a current called the endolymphatic potential, with positivity inside the scala media and negativity outside its wall.
