Summary: We study a nonlinear Langevin equation involving two fractional orders $\alpha \in (0,1]$ and $\beta \in (1,2]$ with three-point boundary conditions. The contraction mapping principle and Krasnoselskii's fixed point theorem are applied to prove the existence of solutions for the problem. The existence results for a three-point third-order nonlocal boundary value problem of nonlinear ordinary differential equations follow as a special case of our results. Some illustrative examples are also discussed.
