Wexford is the county town of County Wexford, Ireland. Wexford lies on the south side of Wexford Harbour, the estuary of the River Slaney near the southeastern corner of the island of Ireland. The town is linked to Dublin by the M11/N11 National Primary Route; and to Rosslare Europort, Cork and Waterford by the N25. The national rail network connects it to Dublin and Rosslare Europort. It had a population of 20,188 according to the 2016 census.

The town was founded by the Vikings in about 800 AD. They named it Veisafjorõr, meaning "inlet of the mud flats", and the name has changed only slightly into its present form. "Vei" in modern Norwegian means "Way". So 'Veisafjorõr' could have meant "inlet of the way" or "Way Fjord". According to a story recorded in the Dindsenchas, the name "Loch Garman" comes from a man named Garman mac Bomma Licce who was chased to the river mouth and drowned as a consequence of stealing the queen's crown from Temair during the feast of Samhain.

For about three hundred years it was a Viking town, a city-state, largely independent and owing only token dues to the Irish kings of Leinster. However, in May 1169 Dermot MacMurrough, King of Leinster and his Norman ally, Robert Fitz-Stephen besieged Wexford. The Norse inhabitants resisted fiercely until the Bishop of Ferns persuaded them to accept a settlement with Dermot.

Wexford was an Old English settlement in the Middle Ages. An old dialect of English, known as Yola, was spoken uniquely in Wexford up until the 19th century. The Yola name for Wexford was Weiseforthe.

Following the Crusades, the Knights Templar had a presence in Wexford. Up to the present, their name is perpetuated in the old Knights' Templars' chapel yard of St. John's Cemetery, on Wexford's Upper St. John's Street.

Places of interest include:

• Curracloe Beach, approximately 10 km north of Wexford town, was the location in 1997 for the opening scenes of Saving Private Ryan.[11]
• The Irish National Heritage Park at Ferrycarrig includes various exhibits spanning 9000 years of Irish history, allowing the visitor to wander around re-creations of historic Irish dwelling including crannogs, Viking houses and Norman forts. The grounds also feature the archaeological site of Newtown, considered the first Norman fortification in Ireland.
• The Wexford Wildfowl Reserve is a Ramsar site based on mudflats, (known locally as slobland), just outside Wexford. It is a migratory stop-off point for thousands of ducks, geese, swans and waders. Up to 12,000 (50% of the world's population) of Greenland white-fronted geese spend the winter on the Wexford slobs. There is a visitor centre with exhibitions and an audio-visual show.
