Field Marshal Francis Wallace Grenfell, 1st Baron Grenfell, GCB, GCMG, PC (Ire) (29 April 1841 – 27 January 1925) was a British Army officer. After serving as aide-de-camp to the Commander-in-Chief, South Africa, he fought in the 9th Xhosa War, the Anglo-Zulu War and then the Anglo-Egyptian War. He went on to become Sirdar (Commander-in-Chief) of the Egyptian Army and commanded the forces at the Battle of Suakin in December 1888 and at the Battle of Toski in August 1889 during the Mahdist War. After that he became Governor of Malta and then Commander-in-Chief, Ireland before retiring in 1908.
Grenfell became Deputy Sirdar (Commander-in-Chief) of the Egyptian Army in late 1882 and, after commanding the Egyptian troops stationed at Aswan during the Nile Expedition, he became Sirdar himself in April 1885. He was appointed Companion of the Order of the Bath on 25 August 1885, and having led his troops at the Battle of Ginnis in December 1885, was promoted to the substantive rank of lieutenant-colonel on 7 January 1886. He was advanced to Knight Commander of the Order of the Bath on 25 November 1886.

In recognition of the transformation he had achieved in making the Egyptian Army a successful fighting force, he was appointed a Knight Grand Cross of the Order of St Michael and St George (GCMG) on leaving Egypt on 25 May 1892.
