This paper presents the complete QED contribution to the electron g-2 up to the tenth order. With the help of the automatic code generator, we have evaluated all 12672 diagrams of the tenth-order diagrams and obtained 9.16 (58)(α/π)⁵. We have also improved the eighth-order contribution obtaining -1.9097(20)(α/π)⁴, which includes the mass-dependent contributions. These results lead to aₑ(theory)=1 159 652 181.78 (77) × 10⁻¹². The improved value of the fine-structure constant α⁻¹ = 137.035 999 174 (35) [0.25 ppb] is also derived from the theory and measurement of aₑ.
