<jats:p>Lung cancer has a very high mortality-to-incidence ratio, representing one of the main causes of cancer mortality worldwide. Therefore, new treatment strategies are urgently needed. Several diseases including lung cancer have been associated with the action of reactive oxygen species (ROS) from which hydrogen peroxide (H<jats:sub>2</jats:sub>O<jats:sub>2</jats:sub>) is one of the most studied. Despite the fact that H<jats:sub>2</jats:sub>O<jats:sub>2</jats:sub>may have opposite effects on cell proliferation depending on the concentration and cell type, it triggers several antiproliferative responses. H<jats:sub>2</jats:sub>O<jats:sub>2</jats:sub>produces both nuclear and mitochondrial DNA lesions, increases the expression of cell adhesion molecules, and increases p53 activity and other transcription factors orchestrating cancer cell death. In addition, H<jats:sub>2</jats:sub>O<jats:sub>2</jats:sub>facilitates the endocytosis of oligonucleotides, affects membrane proteins, induces calcium release, and decreases cancer cell migration and invasion. Furthermore, the MAPK pathway and the expression of genes related to inflammation including interleukins, TNF-<jats:italic>α</jats:italic>, and NF-<jats:italic>κ</jats:italic>B are also affected by H<jats:sub>2</jats:sub>O<jats:sub>2</jats:sub>. Herein, we will summarize the main effects of hydrogen peroxide on human lung cancer leading to suggesting it as a potential therapeutic tool to fight this disease. Because of the multimechanistic nature of this molecule, novel therapeutic approaches for lung cancer based on the use of H<jats:sub>2</jats:sub>O<jats:sub>2</jats:sub>may help to decrease the mortality from this malignancy.</jats:p>
