Which country does the name of coffee mocha come from?

A caffè mocha also called mocaccino, is a chocolate-flavored variant of a caffè latte. The name is derived from the city of Mocha, Yemen.

Mocha is famous for being the major marketplace for coffee (Coffea arabica) from the 15th century until the early 18th century. Even after other sources of coffee were found, Mocha beans (also called Sanani or Mocha Sanani beans, meaning from Sana'a) continued to be prized for their distinctive flavor—and remain so even today. The coffee itself did not grow in Mocha, but was transported from places inland to the port in Mocha, where it was shipped abroad.
