thumb|Grenfell in 1929

Edward Charles Grenfell, 1st Baron St Just (29 May 1870 – 26 November 1941), was a British banker and politician.

His father, Henry Riversdale Grenfell, was Governor of the Bank of England between 1881 and 1883. William Grenfell, 1st Baron Desborough, was his first cousin. where he was secretary of the Pitt Club. On graduation, he immediately entered a career in banking with a position in Brown Shipley, and subsequently with Smith Ellison, moving to J. S. Morgan & Co. in 1900. In 1904, Grenfell became a partner in the bank and in 1910, when J. P. Morgan restructured his London bank, it was renamed Morgan, Grenfell & Co. to reflect his position as senior partner. This led to the 1935 City of London by-election, at which there was no contest. Lord St Just died on 26 November 1941, aged 71, and was succeeded in the barony by his only child Peter George Grenfell (1922–1984).
