This fall sees the return of CW’s Supergirl for her 4th season. With it being the time of year that the CW shows return to Network TV it’s always an exciting time to be a Superhero fan. So when will season 4 be on Netflix? We’ve got everything you need to know about when Supergirl season 4 will be on Netflix US and other regions.

Supergirl originally debuted on the Television Network CBS and after the first season, the show moved over to the CW. CBS is the owner of CW, therefore, the transfer of the show to a separate network was easy to carry out.

Supergirl is the fourth DC Comics show the CW acquired after Arrow, The Flash and DC Legends of Tomorrow.

What to expect in Season 4 of Supergirl


We said goodbye to many characters in season 3 closing story threads that were built up over the course of the 3 seasons. Mon-El returned to future and won’t be returning to Supergirl.

J’onn stepped down as the leader of the DEO and was replaced by Alex. After Kara’s battle resulting in Reign’s death, it is revealed the ‘Black Rock’ used in the fight is now being tested by Lena. At the end of season 3, it was revealed a doppelganger of Kara is now living in a military base in Siberia.

Over the course of the season, the show’s story will take inspiration from the Superman Arc ‘Red Sun’.

Supergirl Season 4 Netflix US Release Date

Supergirl is part of The CW’s contract that allows Netflix to stream the show soon after the season has concluded. It used to be the case that you’d have to wait months after the finale aired before it dropped but nowadays, you only have to wait up to 2 or 3 weeks.

Season 3 of Supergirl concluded on June 18th 2018 and was available to stream on Netflix from the end of June.

Season 4 is following the exact same release schedule on The CW. New episodes start on the channel from October 14th, 2018 and depending on how many episodes are in season 4, will wrap up in late May or throughout June. That means season 4 of Supergirl will be on Netflix sometime in June or July 2019.

Other Regions Netflix Release Dates

There aren’t many regions that are streaming Supergirl outside of the US.

Netflix in Canada, the Netherlands, Israel, and the Czech Republic will get the new season between July and October 2019.

Other regions will have a longer wait as most are still yet to receive season 4.

For those in the United Kingdom, the television network Sky has the exclusive rights to stream the DCU content.

You’ll only find the new season streaming on Now TV and Sky Go.
