Watch The Flash season 9 online

Well that was quick. It's almost time for The Flash to bow out, as the ninth and final season arrives on TV screens from 8th February. New episodes of The Flash season 9 are free to watch on in the US. There's no word as to when the last-ever series will arrive in the UK. Use a VPN to watch The Flash S9 from anywhere, if you happen to be away from home. 

The Flash season 9 preview

The Flash has had a remarkable run – if you'll excuse the pun – given that it started life as a spinoff. Grant Gustin first pulled on The Flash's spandex bodysuit back in 2013 for a supporting role in the series Arrow. That led to a pilot and eventually full The Flash series in 2014 set in Central City.

Now we're nine seasons deep, and things are getting serious. This will be the final season of The Flash, bringing a close to the Arrowverse, and seeing Barry Allen / The Flash hang up his forensic scientist's lab coat / spandex bodysuit for good. So what's in store?

We'll see more crossovers, with Stephen Amell set to return as Oliver Queen / Green Arrow this series. The new negative speed force avatar we saw teased in the season 8 finale is also thought to play a major part in season 9.

The series will continue its graphic novel format, just like past seasons. Its 13 episodes will be broken down into two graphic novel storyline arcs – the eighth and ninth, respectively. These will involve "at least two separate big bads, one of whom is a blast from the past," according to showrunner Eric Wallace.

The Flash season 9 episode 1 premieres on 8th February on CW, and will be available to stream for free at the following day. New episodes air weekly. Follow our guide below to watch The Flash season 9 online from anywhere.

Can I watch The Flash season 9 in the UK?

Yes, but not yet. Sky has been home to every season of The Flash since it started in 2014, but it hasn't announced a transmission date for season 9. Season 8 aired around two weeks after its US transmission date, so you might have to wait a fortnight. Good luck avoiding those spoilers...
