Mid Dorset and North Poole is a constituency[n 1] represented in the House of Commons of the UK Parliament since 2024 by Vikki Slade, a Liberal Democrat.

[n 2] 1997–2010: The constituency was created in 1997 from parts of the seats of North Dorset (Corfe Mullen Central, Corfe Mullen North, Corfe Mullen South, Lytchett Matravers, and Lytchett Minster wards), Poole (Broadstone, Canford Heath, Canford Magna, and Creekmoor wards), South Dorset (Bere Regis, St Martin, and Wareham wards), and Bournemouth West (Alderney ward).

2024–present: Boundaries expanded following re-organisation of local authorities and wards in Dorset, bringing the electorate within the permitted range.

This area includes two tourist towns, namely Wimborne Minster and Wareham, the latter at one end of Poole Harbour.

Income levels are close to the national average, taking into account the high proportion of pensioners living across the area.
