You can currently watch The Mentalist on a few major streaming platforms, plus via digital purchase options.

Main streaming options

  • Hulu – All seasons are available to stream with a paid subscription.
  • Disney Plus (via Roku listing) – Roku’s guide shows it as streamable on Disney Plus in some regions, again with a subscription. Availability can vary by country, so you may or may not see it in your catalog.
  • Subscription TV apps / bundles – In some countries it appears via local services like NOW or similar cable-linked streamers, so it’s worth checking any bundled TV apps you already use.

Tip: The exact answer to “where can I watch The Mentalist” will depend on your country, and catalogs change over time, so always search the title directly in your local apps.

Where to buy or rent digitally

If it’s not on a subscription service where you live, you can buy episodes or full seasons :

  • Amazon Video / Prime Video Store – HD purchase per episode or per season.
  • Apple TV (iTunes) – Also offers the show for digital purchase.
  • Fandango at Home (formerly Vudu) – Listed as a place to buy episodes in HD.

These stores usually let you keep permanent access to purchased seasons in your library.

Free viewing and “sketchy” sites

Official guides note no fully free, legal streaming option for the whole series right now. Forum threads often mention various free streaming sites, but many of these are unofficial, region‑dependent, and can change or disappear quickly, and they often raise security and legality concerns.

For a safe, hassle‑free experience, sticking to Hulu, Disney Plus where available, or the major digital stores is your best bet.

TL;DR: If you’re asking “where can I watch The Mentalist” right now, check Hulu first; if it’s not there in your region, search Disney Plus and any local TV apps, or buy it on Amazon Video, Apple TV, or Fandango at Home.
