Rosal de la Frontera is a municipality of Spain located in the province of Huelva, Andalusia.

Located in the south-west of the Iberian Peninsula, the village lies at about 219 m above sea level,[2] near the right bank of the Chanza River.

The N-433 [es] national road cuts across the municipality and the village, connecting the latter with the Portuguese border (which is barely 3.8 km to the West)[3] and, a bit farther, the Portuguese freguesia of Vila Verde de Ficalho.

[4] The area of the Chanza riverbanks was already inhabited in the Neolithic and there is a megalithic stone circle known as "Pasada del Abad [de]" near the village of Rosal, and within the municipal limits.

[5][6] As the Portuguese Restoration War broke out, many small settlements near the border depopulated, with the inhabitants withdrawing to the bigger villages, eventually leaving the rest of the territory open to smuggling and banditry.
