Sir John Merry le Sage (23 April 1837 – 1 January 1926), was a British journalist and newspaper editor.

He enjoyed a good relationship with first Joseph Moses Levy and then his son Edward Levy-Lawson, successive owners of the Daily Telegraph.

When the senior Levy died, Le Sage was named as editor, though Levy-Lawson exercised firm control over the newspaper until he became Baron Burnham in 1903.

As editor, Le Sage continued the traditions laid out by his predecessors, focusing on the middle class reader and ignoring criticism of his practices.

Hampered by his age and an unwillingness to delegate responsibility, he nonetheless continued on as editor and was knighted in 1918 in recognition for his services to journalism.
