Algebraliens, or Algebralians as the name is sometimes spelled, are a genderless race from the universe of BFDI.

They are brightly colored creatures with round nubby bodies shaped like various numbers, letters, and symbols. They tend to be grouped into different categories based on the symbol they represent, such as integers, variables, and operators. Not all algebraliens are humanoid, many lack a distinct head and body. Each algebralien tends to be one solid hue, with slightly paler limbs. When squeezed, their bodies have unique textures that vary by individual, with some feeling squishy, some being rubbery, and some being hard like lead.

Algebraliens have the potential to have reality warping powers, though not all characters have them.

In the BFDI fandom, it is popular to create fansonas and OCs of this species. Fanartists often depict them with fur and paws, despite there being no canon evidence supporting this.
