Law of the Timber is a 1941 American western film directed by Bernard B. Ray and starring Marjorie Reynolds, Monte Blue and J. Farrell MacDonald.

Henry Lorimer is one of the two owners of downsized H & L Lumber Company camp, who returns one day to give the good news that he has negotiated a new contract with the U.S. government.

The plan is to cut down the entire tree population in Antler Valley, a place where lumbering previously has been impossible because of the resistance from the fierce inhabitants.

A young man named John Gordon comes looking for a job, and flirts with Lorimer's daughter Perry as soon as he enters the company premises.

The camp manager, Frank Barnes, asks Perry to marry him, and Adams tries to buy her share of the company, but she refuses them both.

The next accident is a dynamite explosion that causes the earth to move and stop the lumber transport by train to its destination at the sawmill.

He also reveals to her that he is the son of late owner Hamilton, who got a share of the company as inheritance on the condition he serve as a lumberjack for some time.
