MEMORANDUM **

Nathan Spencer, a California state prisoner, appeals pro se from the district court’s judgment dismissing his 42 U.S.C. § 1983 action for failure to exhaust administrative remedies under the Prison Litigation Reform Act, 42 U.S.C. § 1997e(a). We have jurisdiction under 28 U.S.C. § 1291. We review de novo the district court’s dismissal for failure to exhaust, and for clear error its factual determinations, Wyatt v. Terhune, 315 F.3d 1108, 1117 (9th Cir. 2003), and we affirm.

The district court properly dismissed the action because Spencer failed to exhaust administrative remedies prior to filing suit. See Woodford v. Ngo, 548 U.S. 81, 93-95, 126 S.Ct. 2378, 165 L.Ed.2d 368 (2006) (holding that “proper exhaustion” under section 1997e(a) is mandatory and requires adherence to administrative procedural rules); see also McKinney v. Carey, 311 F.3d 1198, 1199 (9th Cir. 2002) (per curiam) (inmates are required to exhaust administrative remedies prior to filing suit in federal court).

*633 Spencer’s remaining contentions are unpersuasive.

AFFIRMED.
