George Nicol (1740 - June 25, 1828) was a Scottish bookseller and publisher active in in 18th-century London. Nicol was born in Scotland, but relocated to London in 1769 to work with his uncle, the Strand bookseller David Wilson (17?? - 1777). The two eventually became full business partners, enjoying immense success. When Wilson died in 1777, Nichol took over the business in full. In 1781, Nicol was appointed official bookseller to King George III, a position he maintained until 1820. In 1787 he relocated to Pall Mall, acquiring 51 and 58 Pall Mall, one as a shop and the other as living quarters. Around 1800, his son George Nicol joined the firm, and it was renamed George and William Nicol. When the elder Nichol died in 1828, the firm continued as William Nicol until 1855.
