Wren & Martin refers to a single book High School English Grammar and Composition or collectively, a series of English grammar textbooks written jointly by P. C. Wren and H. Martin. Written primarily for the children of British officers residing in India, these books were widely adopted by Indian and Pakistani schools in the post-colonial era and missionary schools in Burma. The books were published in 1935, with a discussion on composition added later. The content in the books is largely based on The Manual of English Grammar and Composition by J. C. Nesfield.
