Historic roads (or historic trails in the US and Canada) are paths or routes that have historical importance due to their use over a period of time. Examples exist from prehistoric times until the early 20th century. They include ancient trackways, long-lasting roads, important trade routes, and migration trails. Many historic routes, such as the Silk Road, the Amber Road, and the Royal Road of the Persian Empire, covered great distances and their impact on human settlements remain today.

The Post Track, a prehistoric causeway in the valley of the River Brue in the Somerset Levels, England, is one of the oldest known constructed trackways and dates from around 3800 BCE. The world's oldest known paved road was constructed in Egypt some time between 2600 and 2200 BC.

The Romans were the most significant road builders of the ancient world. At the peak of the Roman Empire there were more than 400,000 kilometres (250,000 miles) of roads, of which over 80,000 kilometres (50,000 mi) were stone-paved. Another empire, that of the Incas of pre-Columbian South America, also built an extensive and advanced transportation system.

Much later historic roads include the Red River Trails between Canada and the US, from the 19th century. Such pioneer trails often made use of ancient routes created by indigenous people.

The Silk Road was a major trade route between China and India, Europe, and Arabia. It derives its name from the lucrative trade in silk carried out along its length, beginning in the Han dynasty (207 BCE–220 CE). The Han dynasty expanded the Central Asian section of the trade routes around 114 BCE through the missions and explorations of the Chinese imperial envoy Zhang Qian. The Chinese took great interest in the safety of their trade products and extended the Great Wall of China to ensure the protection of the trade route.

Prior to the Silk Road an ancient overland route existed through the Eurasian Steppe. Silk and horses were traded as key commodities; secondary trade included furs, weapons, musical instruments, precious stones (turquoise, lapis lazuli, agate, nephrite) and jewels. This route extended for approximately 10,000 km (6,200 mi). Trans-Eurasian trade through the Steppe Route precedes the conventional date for the origins of the Silk Road by at least two millennia.

The Shudao (Chinese: 蜀道; pinyin: Shǔdào), or the "Road(s) to Shu", is a system of mountain roads linking the Chinese province of Shaanxi with Sichuan (Shu), built and maintained since the 4th century BC. Technical highlights were the gallery roads, consisting of wooden planks erected on wooden or stone beams slotted into holes cut into the sides of cliffs. The roads join three adjacent basins separated and surrounded by high mountains. Like many ancient road systems, the Shu Roads formed a network of major and minor roads with different roads being used at different historical times. However, a number of roads are commonly identified as the main routes.
