Charles Magniac (1827 – 23 November 1891) was a British financier and Liberal politician who sat in the House of Commons in two periods between 1868 and 1886.
Following education at Eton College and the University of Cambridge, he worked in finance in the City of London, becoming a partner in Matheson and Company of Lombard Street.
A contemporary political reporter commented: "St Ives, (Cornwall) scared away Mr Paull (C), and embraced Mr. Magniac (L), of the firm of Matheson & Co., the frightfully rich China merchants in the City, who when they lose a quarter of a million [pounds] are no more concerned about it than I should be if I were to lose half a crown.
