DeJuan Thornton, a federal prisoner, appeals the district court’s 1 order committing him for treatment under 18 U.S.C. § 4245. To be timely, Mr. Thornton’s notice of appeal from the final judgment, entered on March 6, 2015, had to be filed by May 5, 2015. See Fed. R.App. P. 4(a)(1)(B) (providing 60 days to appeal in civil case involving government as party). The notice of appeal was filed on May 26, 2015. Even if we were to consider it to have been filed on May 19 — the date it bears, cf. Fed. R.App. P. 4(c)(1) (prison mailbox rule) — it would still be untimely, and therefore we lack jurisdiction over this civil appeal. See Dieser v. Cont’l Cas. Co., 440 F.3d 920, 923 (8th Cir. 2006) (holding that requirement of timely notice of appeal is mandatory and jurisdictional, and that federal court will raise jurisdiction issues sua sponte).

Accordingly, the appeal is dismissed, and the pending motions are denied as moot.
