Hearts Aflame is a 1923 American silent melodrama film directed by Reginald Barker and starring Frank Keenan, Anna Q. Nilsson, and Craig Ward.

The son of a retired timber baron meets and falls in love with a Michigan woman who refuses to sell her land unless the buyer promises to replant to replace the trees that are to be cut down.

As described in a film magazine,[2] retired millionaire lumberman Luke Taylor (Keenan) sends his son John (Ward) to Michigan to salvage some logs.

While John is there he meets Helen Foraker (Nilsson), who owns a vast amount of uncut timber but refuses to sell unless the purchaser consents to replant the trees.
