Stella Maris is an international agency of the Catholic Church that provides pastoral care to seafarers, other maritime workers, and their families.

A Sailortown is a district in seaports that catered to transient seafarers. These districts frequently contained boarding houses, public houses, brothels, tattoo parlours, print shops, shops selling nautical equipment, and religious institutions offering aid to seamen; usually there was also a police station, a magistrate's court and a shipping office. Because it took several days, in the past, to unload ships, crews would spend this time in sailortown. These were "generic locations—international everyplaces existing in nearly every port." Cecily Fox Smith wrote that 'dockland, strictly speaking, is of no country—or rather it is of all countries'". Sailortowns were places where local people, immigrants, social and religious reformers, and transitory sailors met.
