Sideropora is a genus of colourful and colonial stony corals found in the Indian and Pacific Oceans.

These corals have a distinctive branching and plate-like growth form, with vibrant hues ranging from pink, purple, blue, and yellow. Sideropora colonies provide essential habitat for a variety of marine organisms, including small fish and invertebrates. These corals also play a crucial role in reef ecosystems by filtering the water and providing structure and protection for other reef-building organisms. However, like many coral species, Sideropora is vulnerable to various threats, including climate change, pollution, and overfishing, which can lead to its decline.
