Midlothian North and Musselburgh

Midlothian North and Musselburgh is a constituency of the Scottish Parliament (Holyrood) covering parts of the council areas of Midlothian and East Lothian. It elects one Member of the Scottish Parliament (MSP) by the plurality (first past the post) method of election. It is one of nine constituencies in the Lothian electoral region, which elects seven additional members, in addition to the nine constituency MSPs, to produce a form of proportional representation for the region as a whole.

The seat was created for the 2011 Scottish Parliament election, and covers areas that were formerly part of the constituencies of Midlothian and Edinburgh East and Musselburgh, both of which were abolished. It has been held by Colin Beattie of the Scottish National Party since creation.

As a result of the second periodic review of Scottish Parliament boundaries in 2025, the constituency will be abolished from the 2026 Scottish Parliament election. Most of the area will form the new constituency of Midlothian North, whilst the Musselburgh area will be added to the new constituency of Edinburgh Eastern, Musselburgh and Tranent.
