Which Squib Harry Potter Characters Appear In Canon Books?

I get a kick out of the little details J.K. Rowling drops about the wizarding world, and the topic of squibs is one of those tiny, bittersweet corners that really lingers. If you only want the blunt list from the books: the two squibs who actually appear on the page are Argus Filch and Arabella Figg. Filch is impossible to miss — the cantankerous caretaker at Hogwarts with his cat Mrs. Norris, always prowling corridors and moaning about rule-breaking. His squib status is used to explain a lot of his bitterness and his obsessive attachment to the school’s rules, since he’s lived inside a magical place his whole life but never had the magic himself.

Arabella Figg is quieter but equally important. She turns up as a seemingly ordinary neighbor who looks after Harry sometimes and later testifies in 'Order of the Phoenix' about the Dementor attack. She’s a squib who’s been involved in the Order’s network, and that contrast — living in the Muggle world while being plugged into the wizarding community — makes her role emotionally interesting. A lot of her portrayal shows how squibs can be bridge figures: socially awkward in both worlds in different ways, but valuable for perspective.

People often get mixed up and throw other non-magical characters into the “squib” bucket — Petunia Dursley, for example, is non-magical but not a squib (she isn’t born to magical parents). The books make that distinction clear enough if you look for it: squibs are born to magical families and lack the ability, while Muggles are non-magical by birth with no wizarding lineage. Outside the seven books, J.K. Rowling has expanded on the world in interviews and on her site, which sometimes confuses fans about who’s “canon” as a squib, but sticking strictly to the novels keeps it tidy: Filch and Figg are your on-page examples. I like how their presence quietly highlights the costs and oddities of living between worlds — it always gives me a little pang of sympathy for both of them.

I'll keep this short and chatty: in the canonical books there are two squibs who actually show up — Argus Filch and Arabella Figg. Filch is the grumpy Hogwarts caretaker you see in multiple books; his lack of magic explains a lot about his sour attitude and why he clings to rules and his cat. Figg is the unassuming neighbor who appears significantly in 'Order of the Phoenix' (and is mentioned Elsewhere); she’s a squib who’s involved with the Order and gives a different, more tender perspective on being non-magical in a magical family.

Fans sometimes lump other non-magical characters into the squib category, but that’s a mistake: Petunia is a Muggle, not a squib, since she wasn’t born to magical parents. The books make the distinction pretty clear, and I appreciate how the two squibs we actually meet add real texture to the world — they aren’t flashy, but they’re unforgettable in their own way.
