TGV inOui is the brand name of premium TGV train services operated by SNCF since 27 May 2017 on certain high speed rail services.{{Cite news|date=2017-05-28|title=Nouvelle stratégie commerciale à la SNCF|language=fr-FR|work=La Croix|url=https://www.la-croix.com/Economie/France/Nouvelle-strategie-commerciale-SNCF-2017-05-28-1200850744|access-date=2020-05-14|issn=0242-6056|archive-date=2020-06-14 |archive-url=https://web.archive.org/web/20200614083437/https://www.la-croix.com/Economie/France/Nouvelle-strategie-commerciale-SNCF-2017-05-28-1200850744|url-status=live}} SNCF is in the process of replacing 'classic' TGV services with the premium inOui and low-cost Ouigo brands in preparation for the future opening of France's high-speed rail infrastructure to competition. The name 'inOui' was adopted partly because it resembles the French word inouï meaning “extraordinary” (or literally, “unheard of”).{{Cite web|title=Why we renamed TGV service 'inOui'|url=https://www.connexionfrance.com/People/Interviews/Why-we-renamed-TGV-service-inOui|website=The Connexion|access-date=2020-05-28|archive-date=2021-02-05 |archive-url=https://web.archive.org/web/20210205093513/https://www.connexionfrance.com/People/Interviews/Why-we-renamed-TGV-service-inOui|url-status=dead}}
