Sir John Aird, 1st Baronet (3 December 1833 – 6 January 1911) was an English civil engineering contractor of the late 19th and early 20th centuries.

The business had initially focused on gas and water network installations, but soon expanded into more general building work.

Sir John and his son Malcolm were present in Egypt for the opening of the dam in December 1902,[1] during which he received the Grand Cordon of the Order of the Medjidie from the Khedive.

Aird married Sarah Smith of Lewisham on 6 September 1855 and they had eight children: John (who became, in succession to his father, Sir John Aird, 2nd Baronet), Malcolm, Sarah, Jessie, Ada, Vida, Gertrude, and Dorothy.

John Aird Court, a social housing estate in Little Venice, west London is named after him, in the area which would have formed part of his constituency and been in the original Paddington borough.
