¶2 Gary Cecil, a California state prisoner, appeals pro se from the district court’s order dismissing his 42 U.S.C. § 1983 action alleging due process and access-to-court claims. We have jurisdiction under 28 U.S.C. § 1291. We affirm.
¶3 In his opening brief, Cecil failed to address any of the grounds for dismissal, and has therefore waived his appeal of the district court’s order. See Indep. Towers of Wash. v. Washington, 350 F.3d 925, 929 (9th Cir. 2003) (“[W]e will not consider any claims that were not actually argued in appellant’s opening brief.”); Acosta-Huerta v. Estelle, 7 F.3d 139, 144 (9th Cir. 1993) (issues not supported by argument in pro se appellant’s opening brief are waived).
¶4 AFFIRMED.
