Are The Witcher games Indie?
Honestly, who cares about whether some game is Indie or not. As far as it's a good game - play it :)
MasodikTiasma: Still, CD Projekt Red is an independent studio, since it doesn't belong to any major publisher (CD PROJEKT, CDPR's and GOG's parent company, is a publsher in its own right in Poland).
You can also see that on digital distribution outlets (GOG, Steam, etc.) they are credited as developper and publisher of TW 1 and 2.
Since CDRP own GOG i.e. they are distributors, and they are professional game creators I wouldn't call their games Indie (if it's supposed to mean amateur made games). And there are good Indie games by the way, so it's not a derogatory term in any way.
Belonging to some publisher is not a merit and has nothing to do with the quality of games. I think Indie usually means non professional or low budget projects. Witcher games are very professionally done and are big commercial projects.
