Fasnia is a town and a municipality in the eastern part of the Spanish island of Tenerife, one of the Canary Islands, and part of the province of Santa Cruz de Tenerife.

Etymology
The name of the municipality comes from that of its administrative capital, being a term of Guanche origin that also appears in the historical documentation with the Fasnea variant.[2]
As for its possible meaning, the historian Dominik Josef Wölfel relates it to the Berber word tafessena / tifesseniwin, 'step, rung of a ladder', an opinion that is also accepted by the philologist and historian Ignacio Reyes.
