Christopher Laronn Brown seeks to appeal the district court’s order denying his Rule 60(b) motion. We dismiss the appeal for lack of jurisdiction because the notice of appeal was not timely filed.

When the United States or its officer or agency is a party, the notice of appeal must be filed no more than sixty days after the entry of the district court’s final judgment or order, Fed. R.App. P. 4(a)(1)(B), unless the district court extends the appeal period under Fed. R.App. P. 4(a)(5), or reopens the appeal period under Fed. R.App. P. 4(a)(6). “[T]he timely filing of a notice of appeal in a civil case is a jurisdictional requirement.” Bowles v. Russell, 551 U.S. 205, 214, 127 S.Ct. 2360, 168 L.Ed.2d 96 (2007).

The district court’s order was entered on the docket on May 3, 2011. The notice of appeal was filed on November 22, 2011. * Because Brown failed to file a timely notice of appeal or to obtain an extension or reopening of the appeal period, we dismiss the appeal. We also deny his motion to file a supplemental brief. We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before the court and argument would not aid the decisional process.

DISMISSED.
