Abraham Carel Wertheim, also known as A.C. Wertheim (Amsterdam, 12 december 1832 – Amsterdam, 30 november 1897) was an Amsterdam, the Netherlands, banker, politician, and philantropist. Born into a family of emancipated and enlightened Dutch Jews, he developed his banking and investment skills at Wertheim & Gompertz, an investment firm founded by his uncle Johannes Wertheim. He was subsequently apprentice at prominent banker Julius Königswärter, who introduced him into cultural salons in Amsterdam. Upon his marriage to his cousin Rosalie Marie Wertheim he became a partner in Wertheim & Gompertz. This bank, together with a number of other firms, played a significant role in financing the building of new railroads in the United States.

He was a patron of amateur drama in Amsterdam, and stimulated the development of the (later Royal) Dutch National Theatre Company (Vereeniging Het Nederlandsch Tooneel), soon the only major theatre company in the city. It played at the Municipal Theatre and the Grand Théatre. Wertheim was intimately involved in the rebuilding of the Municipal Theatre on the Leidseplein square after it burnt down in 1890. He was a mason.

As a liberal politician he was a member of the States-Provincial for North Holland (1866-1886) and from 1886 until his death of the Senate.

He was a member of the Order of the Netherlands Lion. He is commemorated in the Wertheimpark in Amsterdam East, which contains a monument dedicated to him.

His brother-in-law was Barend Joseph Stokvis. His nephew was pedagogist Philip Kohnstamm, and his grandchildren were composer Rosy Wertheim and sculptor Jobs Wertheim.
