The continent that contains the country of Madagascar is Africa. Madagascar is the fourth-largest island in the world and is located off the southeastern coast of Africa in the Indian Ocean. It is renowned for its rich biodiversity, with many species found nowhere else on Earth, including the unique lemur. The island's isolation has led to a high level of endemism, making it a focus for conservation efforts. Madagascar's diverse ecosystems range from rainforests to deserts, enhancing its ecological value.
