Sir Andrew Jopp Williams Lewis JP (1875–1952) was a Scottish businessman who served as Lord Provost of Aberdeen.

He was born in the Cove district of Aberdeen on 18 April 1875 the son of John Lewis, owner of J Lewis & Co, boatbuilders, and his wife Elizabeth Williams. He was educated at Aberdeen Grammar School. He was apprenticed as a boatbuilder in his father's company around 1890. In 1907, following his father's death, he took over and renamed the company John Lewis & Sons. He expanded the business, specialising in building and repairing ship engines. They continued their business of building fishing trawlers, but updated this by building refrigerated ships.^[1][2]

Around 1912 he began giving free time as Harbour Commissioner and served on the Aberdeen Harbour Board for 36 years.^[2]

He joined Aberdeen Town Council in 1919 representing the ward of Ferryhill. He was elected Lord Provost in 1925 and served two consecutive two-year terms. During his time in office he raised £410,000 to fund the "Joint Hospitals Scheme" (the equivalent of almost £20 million in 2022) which resulted in a major modernisation of Aberdeen Royal Infirmary and Aberdeen Maternity Hospital (which were not completed until 1936).^[3][4]

He stepped out of local politics in 1929 and was knighted by King George V and awarded an honorary doctorate (LLD) by Aberdeen University^[5] in the same year, and on 10 December 1929 was created Deputy Lieutenant of Aberdeen.^[6]

He died at home in Aberdeen on 2 February 1952.^[7]
