Trelogan is a village in Flintshire, north east Wales. It is located between Mostyn and Trelawnyd and is almost contiguous with Berthengam. Trelogan has a population of approximately 200 people.
The village has its own primary school (Ysgol Gynradd Trelogan), a public house (The Afon Goch), community centre, photographers studio, animal rescue centre and, until 2005, its own post office.
The placename Trelogan derives from the name Logan, the person believed to have founded the village having been named that. The village in history was the locality for several lead-zinc mines, working at least until 1841.
Many people in Japan are familiar with Trelogan, as UK scientists developed a process to plant the semi-toxic, at least to plants, spoil tips from the lead-zinc mines with native UK plant species. Up to this point it had not been possible to grow plants on this type of semi-toxic terrain which was common in Japan due to the many lead-zinc mines in operation.
