In this work, a fractal nonlinear oscillator is established in a fractal space using fractal derivative and its variational principle is obtained. The variational principle provides conservation laws in an energy form, and the approximate frequency of the fractal oscillator is found using a simple fractal frequency formula. An example demonstrates the effectiveness of the fractal frequency formula as a powerful and simple tool for fractal oscillators.
