Medianaa Alta is a barrio located in Loíza, a municipality on the northeastern coast of Puerto Rico in the San Juan metropolitan region. The barrio's name references its elevated topography, situating it in the higher inland areas of Loíza rather than along the coastal zone that defines much of the municipality's character.

Properties in this region tend toward smaller individual parcels mixed with agricultural or undeveloped land, reflecting the historical settlement patterns of municipalities in this part of the island.
