The Amazing Spider-Man 2 (internationally titled The Amazing Spider-Man 2: Rise of Electro) is a 2014 American superhero film based on the Marvel Comics character Spider-Man. Directed by Marc Webb and written by Alex Kurtzman, Roberto Orci, and Jeff Pinkner, based on a story by Kurtzman, Orci, Pinkner and James Vanderbilt, it is the sequel to The Amazing Spider-Man (2012). Andrew Garfield stars as Peter Parker / Spider-Man, alongside Emma Stone, Jamie Foxx, Dane DeHaan, Campbell Scott, Embeth Davidtz, Colm Feore, Paul Giamatti and Sally Field. In the film, Peter Parker tries to protect his girlfriend, Gwen Stacy, as he investigates his parents' death while also dealing with the supervillain Electro and the return of his childhood friend, Harry Osborn.

Development of The Amazing Spider-Man 2 began after the success of The Amazing Spider-Man. DeHaan, Giamatti, Felicity Jones, and Chris Cooper were cast between December 2012 and February 2013. Filming took place in New York City from February to June 2013. The film was released in 2D, 3D, and IMAX 3D on May 2, 2014, in the United States with two international premieres being held between March 31 and April 10 of that year. It received mixed reviews from critics, who praised the chemistry between Garfield and Stone, action sequences, visual effects and Hans Zimmer's musical score, but criticized the screenplay and overabundance of plotlines. Foxx's portrayal of Electro was met with mixed responses. It grossed $716.9 million worldwide, making it the ninth-highest-grossing film of 2014.

The Amazing Spider-Man series was originally intended to continue with at least two more sequels and several spin-offs, most notably films centered on Venom and the Sinister Six. In February 2015, Sony Pictures and Marvel Studios initiated a deal to share the Spider-Man film rights and reboot the character within the Marvel Cinematic Universe (MCU), cancelling future projects in The Amazing Spider-Man film series. Tom Holland would succeed Garfield as Peter Parker / Spider-Man beginning with Captain America: Civil War (2016), while a new standalone film titled Spider-Man: Homecoming would release in 2017, followed by its sequel Spider-Man: Far From Home in 2019, both as part of Phase Three in the MCU. Both Garfield and Foxx reprised their roles in Spider-Man: No Way Home (2021), linking this film to the MCU using the concept of the multiverse.

Former Oscorp scientist and businessman Richard Parker records a video message to explain his disappearance. He and his wife Mary flee aboard a private jet that is soon hijacked by an assassin and crashed, killing the couple.

In the present, one year after his battle with Curt Connors, Richard and Mary's son, Peter, continues to fight crime as Spider-Man and apprehends Russian criminal Aleksei Sytsevich. Due to Peter's reservations about his relationship with his girlfriend Gwen Stacy since making a vow to her late father to avoid her, Gwen ends their relationship after their high school graduation. A few months later, Peter's childhood friend, Harry Osborn, returns home to see his terminally ill father, Norman Osborn, CEO of Oscorp. He explains that his illness is genetic and Harry is at the age where it first develops before dying as his son succeeds him.

While working in an Oscorp laboratory, mild-mannered electrical engineer Max Dillon accidentally electrocutes himself and falls into a tank of genetically engineered electric eels which mutate him into an electrokinetic being. Gwen tells Peter that she may move to England if she earns a scholarship to Oxford University. Unaware of the extent of his power, Max wanders into Times Square, inadvertently causes a power outage and is stopped by Spider-Man as he is then taken to the Ravencroft Institute.

The first symptoms of Harry's illness begin showing and he uses information his father gave him to deduce that Spider-Man's blood could save him. He asks Peter, who has been selling photos of Spider-Man to the Daily Bugle, to aid him in finding Spider-Man. Peter is unsure of what effects the transfusion would have but knows it could cause a mutation similar to Connors. He later refuses Harry as Spider-Man, enraging him. Oscorp vice president Donald Menken frames Harry for covering up Max's accident and usurps him. Harry offers to liberate Max, who now calls himself "Electro", in exchange for getting Harry back inside the Oscorp building; Max agrees.

Upon returning to Oscorp, Harry finds venom from the now-destroyed genetically altered spiders. However, after he forces Menken to inject him with the venom, it accelerates his illness and turns him into a goblin-like being, with the built-in emergency protocol in an armored suit restoring his health. By researching subway tokens hidden in his father's belongings, Peter finds Richard's video message in his secret lab in an abandoned subway station. It reveals he had to flee because he refused to cooperate with Norman's plans to make biogenetic weapons with his research. Richard used his own DNA when he made the spiders, so Oscorp cannot recreate them without his blood. When Gwen is offered the scholarship, Peter professes his love for her and they agree to go to England together.
