What name is given to China's stock-market collapse that began after the June 2015 peak?

China’s stock-market collapse that began after the June 2015 peak is called the 2015 Chinese stock-market crash.

The Shanghai Composite Index reached a major peak in June 2015 after a powerful rally fueled by rising retail participation, margin borrowing, and expectations of continued economic growth. It then fell steeply, losing more than 40% from its high by late August. The Shenzhen market also experienced severe volatility.

Chinese authorities responded with measures including trading restrictions, state-backed purchases, suspension of initial public offerings, and investigations into market activity. These interventions were intended to stabilize prices and limit panic, although they also raised questions about the role of government in the equity market.

The episode is sometimes confused with China’s 2015 currency-market turbulence or with the global “Black Monday” of August 24, 2015. Those events were connected through international risk sentiment, but the Chinese stock-market crash refers specifically to the domestic equity collapse and its surrounding turbulence.
