The Harry Potter story might all be about the younger characters of the show, with Harry, Ron, and Hermione being the driving force of each movie, but other characters provide balance to that. Whether it's teachers at Hogwarts, Death Eaters, or some of the muggles that are involved in the movies, the supporting characters are just as important to the story.

The franchise has some of the greatest actors of all time in these movies, and while not all of them can be found on Instagram, many of them do share their personal lives on that platform. But which of these Harry Potter stars is the most popular?

Ralph Ineson (Amycus Carrow) - 3.7k Followers

Ralph Ineson only has a small role in the final two Harry Potter movies, playing Amycus Carrow, who works alongside Severus Snape in running Hogwarts once Professor Dumbledore has died. He is someone who brings a level of strictness and isn't a popular member of staff with the students.

Ralph plays the role well, even though it's only a smaller part. However, he is a talented actor who has thrived in British television shows, and on Instagram, he often shares images of himself at work, his dogs, and nature.

Tony Maudsley (Grawp) - 11.3k Followers

Tony Maudsley is never someone that people get to see in Harry Potter, but they do get to hear him, as he plays the character of Grawp. He's Hagrid's half-brother and someone who takes a liking to Hermione in the story, which shows a more gentle side of his personality.

Outside of this, Tony is best known for being a comedic character on the hit show Benidorm, while he's also appeared on Coronation Street too, one of Britain's most popular soaps. His Instagram is full of images from the various roles he's undertaken, which is perfect for a fan of his work.

David Thewlis (Remus Lupin) - 24.8k Followers

Remus Lupin is one of the more popular characters to take on the role of Defense Against The Dark Arts teacher. Lupin was a tremendous character and one that provided some terrific advice to Harry at points.

He was a person who had a true heart, but also flair and personality. On Instagram, David Thewlis doesn't have tons of posts, however, he did only create his account in 2021, which is why he's yet to build up the major following.

Chris Rankin (Percy Weasley) - 59.1k Followers

Chris Rankin is coming to the end of his time as a student when Harry Potter begins, and later on, in the movies, he shows up as an adult and a much more experienced wizard. He's someone who is intelligent and likes to do things by the book, and that's what makes him stand out.

Outside of the Wizarding World, Chris Rankin still posts and talks about his time on Harry Potter over on Instagram, which is one of the reasons he's gained such a following on the site.

Warwick Davis (Professor Filius Flitwick) - 103k Followers

Warwick Davis actually played multiple characters throughout the Harry Potter movies. He played Filius Flitwick, who was the charms teacher, while also being a goblin at Gringotts, and as well as the slightly more sinister Griphook as well, making him an important part of this franchise.

Considering he's also involved in the Star Wars franchise, it's no surprise that Warwick Davis has such a strong following on social media. He's a regular poster and a lot of his content is about those two big parts of his life.

John Cleese (Sir Nearly Headless Nick) - 111k Followers

John Cleese has a hilarious Instagram that is worth following for the entertainment factor alone. He often shares funny pictures, with himself being edited onto different characters, while he shares clips and footage of roles he's taken up throughout his career.

In the Harry Potter franchise, John Cleese actually takes on the role of Sir Nearly Headless Nick, who appears in the early movies but then doesn't get used. However, he's kind to Harry and provides some of the funnier moments early on.

Natalie Tena (Nymphadora Tonks) - 118k Followers

The character of Nymphadora Tonks is one that a lot of fans wished had more of the spotlight due to how big of a role she has within the books. However, there's no doubt that she's still a fun character, bringing a lot of charisma to the series whenever she appears.

On Instagram, Natalie Tena has built up a great following with her entertaining feed. She shares lots of images of her travels around the world, which makes her feed quite a vibrant and exciting one to follow for fans.

Clémence Poésy (Fleur Delacour) - 119k Followers

While Fleur Delacour is just a student when she first appears in Harry Potter, by the time the franchise comes to an end she's a fully grown adult enjoying married life. She's someone who works hard to help Harry and the rest of the Order Of The Phoenix, and that's where she really thrives.

She's got a great following on Instagram where she posts updates about her life regularly, with selfies, shots of what's going on around her, as well as posts about different topics and causes that she believes in.

David Tennant (Barty Crouch Jr) - 136k Followers

David Tennant joined the cast for the fourth installment into the Harry Potter franchise, taking on the role of Barty Crouch Jr. He was excellent in this, bringing his huge charisma and personality into the performance, which certainly made it a memorable one.

David's Instagram account works as a promotion for his podcast, where he shares clips with the people he's spoken with and the things they've discussed. Although he does also post occasional photos and videos of himself on there as well.

Jason Isaacs (Lucius Malfoy) - 821k Followers

Lucius Malfoy is a character that audiences hated, and Jason Isaacs did a great job of making him someone who was both stuck up and pompous, but also scared and lacking in confidence. The character was often the right-hand man of Lord Voldemort, but in the end, he wasn't successful at his work.

Despite being an unpopular character, Jason Isaacs was praised for his work on the movies and he ended up being followed by a lot of fans. His Instagram is a popular one and his friendship with Tom Felton, who played his son in the movies is something that fans love to see.
