A fractal curve is, loosely, a mathematical curve whose shape retains the same general pattern of irregularity, regardless of how high it is magnified, that is, its graph takes the form of a fractal. In general, fractal curves are nowhere rectifiable curves — that is, they do not have finite length — and every subarc longer than a single point has infinite length.
An extremely famous example is the boundary of the Mandelbrot set.

Dimensions of a fractal curve
Most of us are used to mathematical curves having dimension one, but as a general rule, fractal curves have different dimensions, also see also fractal dimension and list of fractals by Hausdorff dimension.
Relationships of fractal curves to other fields
Starting in the 1950s Benoit Mandelbrot and others have studied self-similarity of fractal curves, and have applied theory of fractals to modelling natural phenomena. Self-similarity occurs, and analysis of these patterns has found fractal curves in such diverse fields as
- Blancmange curve
- Coastline paradox
- De Rham curve
- Dragon curve
- Fibonacci word fractal
- Koch snowflake
- Mandelbrot set
- Menger sponge
- Peano curve
- Sierpiński triangle
