Abstract：The existence of dark matter is confirmed in astronomy and cosmology. However, the particle nature of dark matter is still unknown. Dark matter direct detection is a kind of experiment which can directly reveal the particle nature of dark matter. Duo to their rapid development in recent years, these experiments become more and more sensitive to dark matter. This review briefly introduces the current status of dark matter direct detection experiments and shows their main results. Some experiments have claimed that some possible dark matter signals have been found. But the results of these experiments are inconsistent to each other. On the other hand, other experiments have excluded these possible signal regions. Further experiments are needed to give a convincing statement.
