Set Chrome’s language using Selenium ChromeDriver

You can do it by adding Chrome’s command line switches “–lang”.

Basically, all you need is starting ChromeDriver with an ChromeOption argument --lang=es, see API for details.

The following is a working example of C# code for how to start Chrome in Spanish using Selenium.

ChromeOptions options = new ChromeOptions();
ChromeDriver driver = new ChromeDriver(options);

Java code should be pretty much the same (untested). Remember, locale here is in the form language[-country] where language is the 2 letter code from ISO-639.

public WebDriver getDriver(String locale){   
    System.setProperty("", "driver/chromedriver.exe");
    ChromeOptions options = new ChromeOptions();
    options.addArguments("--lang=" + locale);
    return new ChromeDriver(options);

public void initializeSelenium() throws Exception{
    driver = getDriver("es"); // two letters to represent the locale, or two letters + country
