Panama City Beach is a city in Bay County, Florida, United States, on the Gulf of Mexico coast. As of the 2010 census it had a population of 12,018. The city is often referred to under the umbrella term of "Panama City", despite being a distinct municipality from the older and larger inland Panama City to the east, making Panama City and Panama City Beach two separate cities. Panama City Beach's slogan is "The World's Most Beautiful Beaches" due to the unique sugar-white sandy beaches of northwest Florida.
