新兴 (xīn xīng) is an adjective meaning 'emerging' or 'newly rising', describing something that is recently developed, gaining prominence, or rapidly growing in importance or influence. The character 新 (xīn) means 'new', and 兴 (xīng) means 'to rise', 'to flourish', or 'to prosper'. Together, they convey the idea of a phenomenon, industry, species, or trend that is newly appearing and beginning to thrive.

This term is commonly used in formal and semi-formal contexts — especially in news reports, academic writing, and policy discussions — to describe sectors like technology, renewable energy, or ecological developments. In zoology, it may refer to newly documented or recently expanding animal populations, such as species adapting to urban environments or emerging invasive species. It carries a neutral-to-positive connotation, emphasizing dynamism and potential rather than instability.
