SamBucky is the slash ship between Bucky Barnes and Sam Wilson from the Marvel Cinematic Universe fandom.

Canon
Bucky and Sam became were close allies when fighting during the accords and had encountered each other when Bucky was still in the hands of HYDRA,

Captain America: The Winter Soldier
Steve, Sam, and Natasha had kidnapped Jasper Sitwell, one of the undercover HYDRA agents working for SHIELD, and had taken the freeway when the Winter Soldier lands on the roof and throws Sitewell out the window and kills him. The Winter Soldier starts to shoot at the three through the roof, and they're able to throw him off. He lands in front of their car just as a HYDRA truck shows up and forces the car forward. Sam tries to stop the car as the Winter Soldier jumps on top of the roof. He then shoves his hand through the front window and takes the wheel out of Sam's hands, and the car crashes.

Steve fights the Winter Soldier, and in the process takes off his mask and reveals him to be Bucky Barnes. As he's about to shoot Steve, Sam flies down and kicks him in the face.

Steve stands at the top of the abandoned dam, Sam coming up to him and tells him that Bucky will be there when they execute their plan. Steve knows. Sam tells Steve that whoever Bucky was, the guy he is now is the kind you stop, not save. Steve says that he doesn't know if he can do that, and Sam says that he might not have a choice, since he doesn't know him.

As Sam and Steve make their way to the helicarrier control room, Bucky rams Steve off the side. Sam goes to get him, but Bucky grabs onto one of his wings and throws him back. Sam stops himself from falling to the ground and starts to shoot at Bucky, who is able to dodge before taking cover. Sam starts to fly away, but Bucky launches a zipline at his wing and slams Sam into the ground. He pulls off the wing and runs towards Sam, and kicks him off the edge of the Helicarrier. Sam is luckily able to land safely at the bottom.

After taking down HYDRA, Sam, Steve and Natasha meet up, and Natasha gives Steve the Winter Soldier file. Sam asks if he's going after Bucky and Steve says that he doesn't have to come with. Sam says he knows, and asks when they start.

Captain America: Civil War
As the power goes out, Steve realizes that the man who framed Bucky is the one interrogating him, and he and Sam run down to the room finding all the guards unconscious. Steve enters the room and confronts the intergator. Sam walks in and a brainwashed Bucky takes a swing at him, Sam ducking just in time. Bucky is able to punch him in the gut and throw him across the room, knocking him out.

Bucky wakes up, his arm locked in a machine, with Sam watching him. Sam calls over Steve and the three start to talk. Steve belives that they're talking to Bucky without mind control, but Sam asks if that makes everything automatically okay. Bucky tells them that Zemo was looking for the other Winter Soldiers. Sam asks if they all turned out like him, and Bucky says that they were worse. Sam tells Steve that this would have been easier a week ago, and they don't know if the accords will allow Tony to help.

The three steel a car and meet up with Sharon Carter for their equipment. While Steve gets their stuff, Sam and Bucky sit in the car, Sam in front, Bucky in back. Bucky asks Sam to move his seat up, but Sam just deadpans "no". Bucky scoots to the side, Sam glancing back at him. They watch Steve kiss Sharon, and when he turns around they both nod their heads and smile, embarrassing him.

As Bucky and Sam run through the airport, they see Spider-Man climb along the outside windows. Bucky asks what that is, but Sam just comments on everyone having a gimmick. Spider-Man then swings around and knocks through the window, and kicking Sam to the side. He then goes to punch Bucky, who stops him, and Sam gets up and flies him away from Bucky.

As Spider-Man chases after Sam, Bucky throws some debris at him to distract him, but it gets thrown back in his face. Sam is brought down by Spider-Man and webbed against the railing. As Spider-Man swings to kick Sam, Bucky runs in front of him and takes the hit, sending them both to the lower floor. Spider-Man webs them both, but Sam sends Red Wing to remove him before he can make an official arrest. Bucky tiredly asks if he couldn't have done that earlier, Sam replying that he hates him.

Behind the Scenes
"I did appreciate any interaction I had with Falcon really enjoyed especially throwing punches at him."

- Sebastian Stan on Backy in Civil War

"Somebody the other day said, 'You know what the real love story is? The Falcon and Winter Soldier.'"

- Sebastian Stan

When a fan at Ace Comic Con asks if Sebastian would ever play an LGBT character again that he would as long as the story is right, just as Anthony Mackie makes his entrance. As Anthony sat down, he pulled Sebastian towards him and placed his arm over his shoulder. Sebastian then stated that said story could happen now.

"It only took about four press tours for someone to kind of get the idea, that these two lunatics, should have a show."

- Sebastian on The Winter Soldier and Falcon

Fanon
Not being a very popular ship among the Marvel Cinematic Universe fandom, there isn't a lot of fanfiction compared to more popular ships, like Stucky or Stony. There were some who shipped them in the comics, and would combine some of their 616 characteristics with their MCU counterparts, which is common for fans of both. Some fans started shipping them from The Winter Soldier most based it on the press tour interviews between actors Anthony Mackie and Sebastian Stan. Given that Marvel has a history of hiring actors who are similar to their characters, it made MCU fans want to see more of Sam and Bucky interact. More started to ship the two after Civil War, given their more shared screen time. With the announcement of the Winter Soldier and Falcon series fans of the pairing were excited. The end of Endgame also set up the two for the series, but also caused many to ship them.

Most ship them based on their more snarky back and forths, specifically saying that they have a more buddy cop dynamic. Many joke about how the only reason they spend time together is because they're both best friends with Steve, and when he's not around they'll instantly start fighting.

After Endgame, the increase in fans of the pairing were due to the end result of the movie. The two were left alone without Steve, and would often use that as a point in current fics of pairing them together.

On AO3, there are over 1800 works, and is the second most written ship for Sam. On Wattpad, there are only 66 stories with the Winterfalcon tag.
