An async chunk in webpack refers to a piece of JavaScript code that is loaded asynchronously or on-demand, rather than as part of the initial page load. It allows modules to be split into separate files and loaded only when they are needed, rather than all at once. This can help improve the initial page load time by reducing the amount of JavaScript that needs to be loaded initially. Async chunks can be created using techniques such as code splitting and dynamic imports in webpack configuration to separate code into different chunks and load them asynchronously when required.
