Barry Allen/Iris West

Barry/Iris, also known as the portmanteau WestAllen in the Arrowverse, is the canon het pairing of Barry Allen (Flash) and Iris West in the Flash fandoms, including CW's The Flash and Young Justice.
==Canon==
===Young Justice===
They appear together in several episodes of Young Justice. They are married and are expecting twins, one of which would be Bart Allen's father.
===Arrowverse===
Pre-canon, Iris and Barry are best friends before his mother is brutally murder by the Reverse Flash at age 11. His father, Henry Allen, is convicted of murdering his mother and lives with Iris and her father, Joe West.
In season 1 of The Flash (2014), Iris West is in a relationship with Eddie Thawne, and they later become engaged. Barry grapples with his feelings for Iris, before giving Iris and Eddie his blessing. Following Eddie's death at the end of the season, Barry and Iris remain close friends but neither of them bring up their romantic feelings. Barry eventually asks Iris out; but Season 2 concludes with his father's death at Zoom's hands; defeating Zoom; and going back in time, thus creating Flashpoint, a timeline where Iris West doesn't know him.
After Barry returns to his original timeline, Iris and Barry begin dating. Barry is soon consumed with the need to save Iris from her impending death at the hands of Savitar; and he asks Iris to marry him in the hope of changing the future. It is actually Iris who eventually defeats Savitar at the end of Season 3; but she loses Barry to the speedforce prison. In the Season 4 premiere, he is released from the speedforce; and they marry mid-season.
On Earth-2, Barry meets Iris' doppelganger, and discovers that Earth-2 Barry Allen is married to her.
===Other Adaptations===
Barry and Iris were together in the first episode of the 1990's The Flash TV series, before breaking up due to differences of where they wanted to take their relationship (Barry proposed, but Iris moved away).
Barry and Iris appeared together in two DCAOM films: Justice League: The New Frontier and Justice League: The Flashpoint Paradox. In The New Frontier, Barry and Iris appear to be together and Iris knows his identity as The Flash. In The Flashpoint Paradox, Barry and Iris are originally married, but by going back in time to save his mother, he loses Iris (she ends up married to someone else). Barry eventually restores the timeline, and they are reunited.
Barry and Iris were previously together in the Injustice: Gods Amongst Men storyline, but broke up due to Barry joining Superman's side.
==Fandom==
While the pairing was always canon in the comics, Barry/Iris was a fairly rare pairing until the CW's The Flash series, which quickly became one of the most popular pairings for the fandom.FFN's Flash comics section is small (216 works as of 9/28/17) - and most of the early works seem to be more focused on the Flash's Rogue Gallery than the speedsters that portrayed Flash, and then later more Bart Allen and Wally West works compared to Barry. Only a handful of works are tagged/grouped under the pairing of Iris & Barry. Doesn't seem to have much LJ presence.
===Young Justice===
Barry/Iris in the Young Justice is very rare in producing fanworks dedicated solely to them. They often appear as a background pairing or secondary characters in Wally West and/or Bart Allen fanworks.
===Arrowverse===
The Barry/Iris fandom termed their pairing name WestAllen, grouping Iris' and Barry's last names together.Pretty sure this appeared in the Arrowverse and not the comics, but someone more familiar might know betterEarliest examples I could find - Ship name discussion on fanforum.com; Page 1
 and Page3 (07/01/2014) accessed on 17th February 2018 It is the second most popular ship in this fandom and the most popular het pairing.
There has been some tension between Westallen fans and fans of other ships within this fandom. See Westallen vs. Snowbarry
====Common Tropes & Storylines====
* Domestic fics often build heavily on their comics backstory, with Future fics depicting Barry and Iris married before their relationship became canon. 
* Established relationship fics were also very common, appearing within a month of the series premiere.
* Alternative Universes - Soulmate AU, Mob AU, Historical AU, College AU
** Canon divergent AUs often involve Westallen getting together earlier. In some works, Flashpoint didn't happen, allowing Iris to remember her second canon kiss with Barry. In others, Barry was not raised in the West household, leading to alternate first meetings
** The CW Multiverse also provides canon AUs, with Earth-2 Iris/Barry appearing in fanworks. In this universe, Iris is a police detective and Barry doesn't have metahuman powers. 
The poly ships of Barry/Eddie/Iris and Barry/Iris/Leonard also appear.
