Tudweiliog (or Dweiliog for short) is a small, predominantly Welsh-speaking village, community and electoral ward on the northern coast of the Llŷn Peninsula in the Welsh county of Gwynedd. It is in the historic county of Caernarfonshire. The population has risen from 801 in 2001 to 970 in 2011. The community includes the small settlement of Llangwnnadl. The community covers just over 35 square kilometres. 
The u in Tudweiliog is a modern addition; before the 1980s the village's name was spelt as Tydweiliog, with a y. There are several versions of the origin of the name:
- One tells of a man called Wil living in a house and known to be lazy; in Welsh, "house" would be Tŷ, his name Wil and finally, "lazy" would be diog, which would combine to make Tywilddiog.
- Another tells of a priest riding his horse (Weiliog) over the sea from Ireland to Porth Towyn beach, and upon arrival the horse left a hoofprint on a stone; after that the priest calls out at the horse: "Tyrd Weiliog" ("Come Weiliog").
- And finally, the third version, and probably the most credible, is that Tudweilog is named after Saint Tudwal who lived in the area at Saint Tudwal's Islands.
Places to stay
Tourism also plays an important role in the village economy during the summer.
There are numerous campsites in and around Tudweiliog and a caravan site. There are also a handful of cottages for rent and B&Bs available to stay at. The local public house also provides a bed-and-breakfast service.
Amenities & attractions
The village has a post office (which also functions as a village store), village hall, public house (the Lion Hotel, the largest building in the village), smithy, parish church, Nonconformist chapel and a primary school, which celebrated its centenary in 2007.
The community has many attractions, including Coetan Arthur, a (burial chamber) on Mynydd Cefnamwlch; Bronze Age remains at the summit of Carn Fadryn; the sandy beaches of Tywyn and Penllech; and the historically important ports of Porth Ysgaden and Porth Colmon at Llangwnnadl, and Porth Gwylan, which is managed by the National Trust.
A local bus service (provided by Nefyn Coaches) provides a connection every one and two hours (7am, 8am and 9am for 1 hour buses, and every 2 hours from 9am onwards) between Tudweiliog and Pwllheli, the nearest market town, approximately 10 miles (16 km) away. The bus stops at other villages on the way, including Nefyn, Dinas, Trefor and Pencaenewydd, depending on which bus is taken.
