We prove the Marcinkiewicz–Zygmund Strong Law of Large Numbers for U-statistics of strictly stationary, absolutely regular observations (ξi)i≥1. Under suitable moment conditions and conditions on the mixing rate, we show that n−2+γ∑1≤i<j≤n(h(ξi,ξj)−Eh(ξ,η))→0 for some γ≥0, in the non-degenerate case, and n−1+γ∑1≤i<j≤n(h(ξi,ξj)−Eh(ξ,η))→0 in the degenerate case.
