The Mid Lanarkshire by-election, 1888 was a parliamentary by-election held on 27 April 1888 for the House of Commons constituency of Mid Lanarkshire in Scotland.
The seat had become vacant in April 1888. The constituency's Liberal Member of Parliament, Stephen Mason resigned from his seat. He did this by being appointed Steward of the Manor of Northstead, a notional offices of profit under the Crown, which is used to permit MPs to vacate their seats as Members of the House of Commons cannot technically resign from their seats.
Mason (1832-21 April 1890) was a Glasgow merchant, who had been the MP for the constituency since the 1885 general election. He was known for having written pamphlets on political topics, such as monetary and land questions, the Anglo-French treaty of 1860 and banking in Scotland.
