Hugh C. MacLean Publications Limited, based in Toronto, Ontario, was a major Canadian publisher, primarily of trade journals such as Canada Lumberman.

Hugh C. MacLean Publications Limited was established around 1909 by Hugh Cameron MacLean, basing the company on the publications of C.H. Mortimer, including Canada Lumberman, which MacLean had purchased in 1907. To these were added numerous other new trade journals, such as Footwear in Canada in 1911, and more acquired titles, such as Furniture and Furnishings in 1919.

The company relocated in 1914 to its own building at 345 West Adelaide Street in Toronto, Ontario. In 1954 Hugh C. MacLean built a modern printery at Don Mills.

In addition to Hugh C. MacLean, executives in the company over the years included: Thomas Seymour Young; Andrew Dyas MacLean; James Alexander Daly; Aubrey Acton Burrows; George Collington; and Samuel Stewart Moore.

The Southam family purchased Hugh C. MacLean Publications Limited and operated it as a separate company, under the name Southam-MacLean Publications Limited, which became Southam Business Publications Limited in 1964.
