Albert Clifford Holliday (1897 - 1960) was a British urban planner and architect active in different parts of the British empire in the early-mid 20th century. He studied under Sir Charles Reilly and Patrick Abercrombie at the University of Liverpool. During the period 1922 - 1935, he was an advisor to the city of Jerusalem and the mandatory government of Palestine. During this period, he conceived an ambitious but ultimately unrealized plan for Jerusalem. Holliday also designed several buildings that were constructed in Palestine, including Jerusalem's Town Hall (now known as the Old Town Hall). Outside of Palestine, he was involved in designing the University of Ceylon and the Stevenage New Town.
