Montagu William Lowry-Corry, 1st Baron Rowton, KCVO, CB, PC, DL (8 October 1838 – 9 November 1903), also known as "Monty", was a British philanthropist and public servant, best known for serving as Benjamin Disraeli's private secretary from 1866 until the latter's death in 1881.

From this time till the statesman's death in 1881 Corry maintained his connection with Disraeli, the relations between the two men being more intimate and confidential than usually subsist between a private secretary and his political chief.

When Disraeli resigned office in 1868 Lowry-Corry declined various offers of public employment to be free to continue his services, now unpaid, to the Conservative leader.

He accompanied Disraeli (who in 1876 had been ennobled as Earl of Beaconsfield) to the Congress of Berlin in 1878, where he acted as one of the secretaries of the special embassy of Great Britain.

He was inspired by projects of that kind founded by Lord Iveagh in Dublin and at the time of his death was chairman of both the Rowton Houses Company and the Guinness Trust.
