Yes, Google Chrome Browser has built-in ad blocker.

Google Chrome can block some of the annoying and intrusive ads on the websites you visit. However, the built-in ad blocker is not very effective and does not block all types of ads.

If you want to enable or disable the built-in ad blocker on Chrome, you can follow these steps:

• Go to Chrome Settings > Advanced Settings.
• Under Privacy and Security > look for Site Settings > Additional content settings.
• Click Intrusive ads.

You can also customize the ad-blocking settings for specific sites by clicking on the padlock icon beside the URL bar and choosing Site Settings > Ads.
