Vágsfjørður is a fjord on the island of Suðuroy in the Faroe Islands. The fjord is located in the southern part and on the eastern side of the island. The distance between the east and the west coast of Suðuroy is very short from Vágsfjørður to Vágseiði. Between the fjord and Vágseiði is a lake which is called Vatnið (The Lake). There are five villages around the fjord. In the bottom of the fjord is Vágur, which is one of the largest of the villages in Suðuroy. Further east on the northern side of the fjord is Porkeri, in between Vágur and Porkeri is the small village Nes, where a famous artist Ruth Smith lived. She drowned while swimming in Vágsfjørður at the age of 45.
On the southern side of Vágsfjørður is Lopransfjørður, where the village Lopra is located along with a small bay called Ónavík. Less than one kilometer from the bay of Ónavík is Lopranseiði on the west coast of Suðuroy. Further south of Lopransfjørður and at the beginning of Vágsfjørður is a small village called Akrar.
Vágs Havn is the harbour of Vágur. The fjord is 10–15 metres deep where the harbour is. The municipality of Vágur made it deeper in 2004, it was a big investment. There are fish factories in the harbour. There is also a ferry port, where the ferry Smyril used to sail to a few times every week, now it only comes to Vágur once every three weeks in order to bunker from the Vágsverkið of SEV which is on the south side of the fjord. When the ferry comes to buker, Smyril first arrives to the port at the northern side in order to let people and cars on shore, after that the ferry sails across the fjord to bunker. After the bunkering, the ferry sails across the fjord again in order to take passengers and cars and cargo on board. Smyril's port in Suðuroy is on Krambatangi in Tvøroyri municipality since the arrival of the current ferry in 2005.
