Ivybridge /ˈaɪvibrɪdʒ/ ^ⓘ is a town and civil parish in the South Hams, in Devon, England. It lies about thirteen miles (twenty-one kilometres) east of Plymouth. It is at the southern extremity of Dartmoor, a National Park of England and Wales and lies along the A38 "Devon Expressway" road. There are two electoral wards in Ivybridge East and Ivybridge West with a total population of 11,851.

Mentioned in documents as early as the 13th century, Ivybridge's early history is marked by its status as an important crossing-point over the River Erme on the road from Exeter to Plymouth. In the 16th century mills were built using the River Erme's power. The parish of Saint John was formed in 1836. Ivybridge became a civil parish in 1894 and a town in 1977.

The early urbanisation and development of Ivybridge largely coincided with the Industrial Revolution. Stowford Paper Mill was built in 1787 and rebuilt again in the 1860s with extensive investment. In 1848 the South Devon Railway arrived on the northern edge of the village. The paper mill closed in 2013 after 226 years in Ivybridge and the buildings are being converted to homes and shops. Ivybridge is often referred to as a commuter town, although a small proportion of people work in the town itself, and agriculture continues to play an economic role for the surrounding area. The area surrounding Ivybridge is varied and complex, including river valleys, farmland and dense woodland.

While heavy industry diminished during the latter half of the 20th century, the population grew significantly from 1,574 people in 1921 to 12,056 in 2001.

The name Ivybridge is derived from a small 13th century hump-backed bridge of the same name. The Ivy Bridge was the only means of crossing the river until the 1830s although plans were put forward in 1819. "Ivy" was used to describe the bridge, because there was ivy growing along the bridge. As the bridge was the centre of the village and important to its very existence, it was named the "parish of Ivybridge" in 1894.

The first mention of a settlement in the Ivybridge area was the manor of Stowford in the Domesday Book of 1086. Although the first mention of Ivybridge came in 1280 when it was described as "dowry of land on the west side of the River Erme, by the Ivy Bridge." There was once a chapel, that was on the site of present-day Saint John's Church, originating from 1402. From the 16th century onwards mills were built in the town, harnessing the power of the river. Records show that in the 16th century there was a corn mill, a tin mill and an edge mill. One of the mills, 'Glanville's Mill' (a corn mill), was situated where many of the town shops are today and gives its name to the shopping centre. The first church (Saint John's) was built in 1790 as a chapel of ease, but 45 years later in 1835 it was consecrated as a district church. The oldest burial in St John's church yard is from 1836. In the 1830s the Ivy Bridge lost its position as the only means of crossing the river when the 'New Bridge' was built joining Fore Street and Exeter Road. Today, this bridge has been modernised so as to carry the increased weight and traffic of the 21st century. Stowford Mill is depicted on a commemorative coin produced for the town of Ivybridge by Bigbury Mint Ltd, based in Ermington near the town. The 25 mm diameter coin also features the town's viaduct which stands at an impressive 104 feet high. The coin was first struck circa 2005 by Bigbury Mint.

In 1977 Ivybridge became a town. Throughout the 1980s and 1990s it underwent a period of rapid growth and was designated as the fastest growing town in Europe, the construction of the A38 "Devon Expressway" adjacent to the town significantly contributed to the town growth during this period.

Ivybridge is represented by five tiers of elected government.
