The Hogwarts school uniform consists of specific articles of clothing required for all attending students. The primary component is a set of simple, plain black work robes, as listed in the first-year equipment list sent to students like Harry Potter. All items of clothing must be marked with the student's name tag. The uniform includes a plain black pointed hat for “day wear,” though students are infrequently depicted wearing them outside of formal events like the Sorting Ceremony. For colder weather, students are required to have a black winter cloak with silver fastenings. While the core robes are plain black, students display their House pride through accessories. It is common for students to wear scarves, hats, and jumpers in their House colours (Gryffindor: scarlet and gold; Slytherin: green and silver; Ravenclaw: blue and bronze; Hufflepuff: yellow and black). Prefect and Head Boy/Head Girl badges are also worn on the robes, displaying the relevant House crest and colours. Separate uniforms are required for Quidditch players, which are brightly coloured according to their House team. For special formal occasions, such as the Yule Ball, students are required to wear dress robes. These vary in style and colour; Harry Potter wore bottle-green robes, while Ron Weasley was forced to wear an archaic, frilly set of second-hand robes. Students are expected to wear their uniform during classes, while travelling on the Hogwarts Express, and for formal school events and examinations like the O.W.L.s and N.E.W.T.s. The rules appear to be more relaxed during evenings and weekends, when students are sometimes seen in Muggle clothing.

The uniform is one of the first elements that introduces Harry Potter—and the reader—to the customs and requirements of the wizarding world. His trip to Madam Malkin's Robes for All Occasions in Diagon Alley is a significant rite of passage, marking his transition from a life of neglect in ill-fitting hand-me-downs to a world where he belongs. The uniform serves as a great equaliser, placing students from vastly different backgrounds, such as the wealthy Draco Malfoy and the impoverished Weasley family, in the same basic attire. However, subtle differences, like the quality of the robes or the state of one's dress robes, are used to highlight issues of class and wealth within the student body. The uniform also visually reinforces the House system, which is a central element of Hogwarts social life and competition.

• Film Adaptations: The film series popularised a different look for the uniform than what is described in the novels. In the films, the Hogwarts uniform includes more Muggle-style school attire worn underneath the robes: a grey V-neck jumper, a white collared shirt, and a tie in the student's House colours. Girls are typically shown wearing skirts and boys wear trousers. The robes themselves are often depicted with coloured linings and a House crest embroidered on the chest (film). This specific design is an invention for the films, as the books describe the robes as plain black.
• Pointed Hats: While listed as a required item for day wear, the pointed hats are almost entirely absent in the films after the Sorting Ceremony in Harry Potter and the Philosopher's Stone (film). In the books, their usage is also minimal after the first year's ceremony.
