Ipswich (/ˈɪpswɪtʃ/ ⓘ) is a constituency[n 1] represented in the House of Commons of the UK Parliament since July 2024 by Jack Abbott of the Labour Party.

Ipswich was seen as a partisan seat with active Blue (Tory inclined) and Yellow (Whig inclined) factions dominating elections for both Parliament and the corporation and comparatively rare split tickets of one Whig and one Tory being returned to Parliament, although the identification of the local parties with national parties could at times be very blurred.

Ipswich is a bustling town that serves as a centre for the rest of Suffolk which is predominantly rural and remote, and has the only serious concentration of Labour voters in the county, other than in Lowestoft.

Portman Road Football Ground to the West of the centre, and the new university to the East are both in the seat, as is the vast Chantry council estate to the South.

Ipswich's Conservative-leaning suburbs, such as Castle Hill, Westerfield and Kesgrave, extend beyond the constituency's boundaries – the northernmost wards are in the Suffolk Central constituency, and several strong Conservative areas are just outside the borough's tightly drawn limits, making Ipswich a target seat for Labour.

The present-day constituency consists of most of the Borough of Ipswich, with the exception of the Castle Hill, Whitehouse and Whitton wards.
