To change the language on Netflix, you need to adjust either the display language (menus, profiles) or the audio/subtitle language for what you’re watching.

1. Change Netflix display language (menus, text)

On phone or tablet (Netflix app)

  1. Open the Netflix app and go to the profile selection screen.
  1. Select the profile you want and tap the Edit (pencil) icon.
  1. Tap Language or Display Language.
  1. Choose your preferred language; it saves automatically.
  1. Tap Done and restart the app if the menus don’t switch right away.

On a browser (computer or mobile)

  1. Go to Netflix in your browser and sign in.
  1. Hover over your profile picture in the top-right and click Account.
  1. In Profile & Parental Controls, choose the profile you want.
  1. Next to Language , click Change.
  1. Pick your display language and save.

On a smart TV / streaming device

  1. Open Netflix and go to the profile selection screen.
  1. Highlight your profile and select the Edit or pencil icon.
  1. Choose Language or Display Language.
  1. Select your preferred language; it saves automatically.

2. Change audio and subtitle language while watching

You can also change only the audio or subtitles for a specific show or movie.

On TV or browser

  1. Start playing a show or movie.
  1. Pause the video to show the player controls.
  1. Select the Audio & Subtitles option or the speech bubble icon.
  1. Choose your preferred audio language and subtitle language.
  1. Close the menu; your choices save automatically for future playback on that profile.

On phone or tablet

  1. Start a show or movie in the app.
  1. Tap the screen, then tap Audio & Subtitles.
  1. Pick the languages you want for audio and subtitles.
  1. Exit the menu; settings save automatically.

3. If Netflix suddenly changed language

Sometimes people open Netflix and everything is suddenly in another language.

  • Check if you’re on the right profile ; each profile has its own language settings.
  • Follow the display language steps above to switch it back to your language.
  • If the menus are in a language you can’t read, you can still use icon positions: top‑right profile picture → first big option that looks like Account → scroll to profile section → look for the row that changed (usually near the top; this is Language).

On community forums, people often discover their language changed because someone else in the household or their account changed settings on another device; switching profile language usually fixes it immediately.

4. Mini FAQ and tips

  • Can each person have a different language?
    Yes, language is set per profile , so one profile can be English and another Spanish or French.
  • Why are some languages missing?
    Available audio/subtitle languages depend on the show and your region, so not all content has every language.
  • Does changing app language change audio automatically?
    Changing display language influences what audio/subtitle options Netflix suggests, but you can still override it per title in the Audio & Subtitles menu.

TL;DR:
Go to your profile settings → Language/Display Language to change the app menus, and use Audio & Subtitles while a video is playing to change audio and subtitle language.
