Major-General Sir George Charles d'Aguilar, KCB (Chinese: 德忌笠; Sidney Lau: Dak¹ Gei⁶ Lap¹ or Chinese: 己立; Sidney Lau: Gei² Laap⁶); January 1784 – 21 May 1855), was a British Army officer who served as Lieutenant Governor of Hong Kong (1843–1848).

He was born the son of Solomon d'Aguilar (1752–1817) of Liverpool and Margaret Gillmer (1753–1829). The d'Aguilars were a military family directly descended from Baron Diego d'Aguilar, a Jewish nobleman and businessman in the court of Maria Theresa of Austria. His first cousin and contemporary, Lieutenant-Colonel George Thomas d'Aguilar (1783–1839) married Catherine Burton, aunt of the noted explorer Sir Richard Francis Burton. Ephraim Lópes Pereira d'Aguilar, 2nd Baron d'Aguilar was an uncle.

He entered the army in 1799 as an ensign with the 86th (Royal County Down) Regiment of Foot which was stationed in India. He remained there until 1808, and during that time served for three years as Adjutant of the 86th Foot (consisting of nearly the whole of Richard Wellesley, 1st Marquess Wellesley's administration) and two years on the general staff of the army, as brigade major.
