Trafalgar is a town in the West Gippsland region of Victoria, Australia. The town lies on the Princes Highway and main Gippsland railway line about 10 kilometres (6 mi) west of Moe. The town backs onto the foothills of the Strzelecki Ranges to the south. The township sits at approximately 70 metres above sea level. At the 2016 census, Trafalgar had a population of 3,912. The town is named in honour of the Battle of Trafalgar, 1805, which established the Royal Navy's supremacy at sea; allowing consolidation of Britain's Australian colonies at the time.
