Poole is a large coastal town and seaport in Dorset, on the south coast of England. The town is 21 miles (34 km) east of Dorchester and adjoins Bournemouth to the east. Since 1 April 2019, the local authority is Bournemouth, Christchurch and Poole Council which is a unitary authority. Poole had an estimated population of 151,500 (mid-2016 census estimates) making it the second-largest town in the ceremonial county of Dorset. Together with Bournemouth and Christchurch, the conurbation has a total population of nearly 400,000.

Human settlement in the area dates back to before the Iron Age. The earliest recorded use of the town's name was in the 12th century when the town began to emerge as an important port, prospering with the introduction of the wool trade. Later, the town had important trade links with North America and, at its peak during the 18th century, it was one of the busiest ports in Britain. In the Second World War, Poole was one of the main departing points for the Normandy landings.

Poole is a tourist resort, attracting visitors with its large natural harbour, history, the Lighthouse arts centre and Blue Flag beaches. The town has a commercial port with cross-Channel freight and passenger ferry services, which connect with the Channel Islands of Jersey and Guernsey, as well as the French port town of Saint-Malo, Brittany.

The headquarters of the Royal National Lifeboat Institution (RNLI) is in Poole, and the Royal Marines have a base in the town's harbour. Despite their names, Poole is the home of The Arts University Bournemouth, the Bournemouth Symphony Orchestra and a significant part of Bournemouth University.

The town's name derives from a corruption of the Celtic word bol and the Old English word pool meaning a place near a pool or creek. Variants include Pool, Pole, Poles, Poll, Polle, Polman, and Poolman. The area around modern Poole has been inhabited for the past 2,500 years. During the 3rd century BC, Celts known as the Durotriges moved from hilltop settlements at Maiden Castle and Badbury Rings to heathland around the River Frome and Poole Harbour. The Romans landed at Poole during their conquest of Britain in the 1st century and took over an Iron Age settlement at Hamworthy, an area just west of the modern town centre. In Anglo-Saxon times, Poole was included in the Kingdom of Wessex. The settlement was used as a base for fishing and the harbour a place for ships to anchor on their way to the River Frome and the important Anglo-Saxon town of Wareham. Poole experienced two large-scale Viking invasions during this era: in 876, Guthrum sailed his fleet through the harbour to attack Wareham, and in 1015, Canute began his conquest of England in Poole Harbour, using it as a base to raid and pillage Wessex.

The natural environment of Poole is characterised by lowland heathland to the north and wooded chines and coastline to the south. The heathland habitat supports the six native British reptile species and provides a home for a range of dragonflies and rare birds. Development has destroyed much of the heath but scattered fragments remain to the north of Poole and have been designated Special Protection Areas. The town lies on unresistant beds of Eocene clays (mainly London Clay and Gault Clay), sands and gravels. The River Frome runs through this weak rock, and its many tributaries have carved out a wide estuary. At the mouth of the estuary sand spits have been deposited, enclosing the estuary to create Poole Harbour.

The harbour is the largest natural harbour in Europe and the second-largest natural harbour in the world after Sydney Harbour. It is an area of international importance for nature conservation and is noted for its ecology, supporting salt marshes, mudflats and an internationally important habitat for several species of migrating bird. It has been designated a Site of Special Scientific Interest (SSSI), a Special Protection Area and a Ramsar site as well as falling within an Area of Outstanding Natural Beauty. The harbour covers an area of 15 square miles (11 sq nmi; 39 km²) and is extremely shallow. The main shipping channels are 7.5 metres (25 ft) deep the average depth of the harbour is 48 centimetres (1 ft 7 in). It contains several small islands, the largest is Brownsea Island, a nature reserve owned by the National Trust and the birthplace of the Scouting movement and location of the first Scout Camp. Britain's largest onshore oil field operates from Wytch Farm on the south shore of the harbour. The oil reservoirs extend under the harbour and eastwards from Sandbanks and Studland for 6.2 miles (10 km) under the sea to the south of Bournemouth.

Situated directly to the east of the Jurassic Coast, Poole is a gateway town to the UNESCO World Heritage Site, which includes 95 miles (153 km) of the Dorset and east Devon coast important for its geology, landforms and rich fossil record. The South West Coast Path stretches for 630 miles (1,010 km) from Minehead in Somerset, along the coast of Devon and Cornwall and on to Poole. The path is England's longest national trail.
