Manual Louis Robinson, Texas prisoner # 1655982, moves for a certificate of ap-pealability (COA) to appeal the district court’s denial of his 28 U.S.C. § 2254 petition challenging his conviction for capital murder, which resulted in a life sentence. Robinson asserts that he received ineffective assistance of counsel at trial. In order to obtain a COA, Robinson must make “a substantial showing of the denial of a constitutional right.” 28 U.S.C. § 2253(c)(2).

This court must examine the basis of its jurisdiction, sua sponte if necessary. Mosley v. Cozby, 813 F.2d 659, 660 (5th Cir. 1987). Robinson’s notice of appeal was filed more than 30 days from the entry of the final judgment denying his § 2254 petition; therefore, it is untimely. See Fed. R. App. P. 4(a)(1)(A), (c)(1). As a federal habeas proceeding is civil in nature, see Archer v. Lynaugh, 821 F.2d 1094, 1096 (5th Cir. 1987), a timely notice of appeal is a jurisdictional requirement. Bowles v. Russell, 551 U.S. 205, 214, 127 S.Ct. 2360, 168 L.Ed.2d 96 (2007). Because Robinson’s notice of appeal was untimely, we lack jurisdiction to address his COA motion.

Accordingly, Robinson’s appeal is DISMISSED for want of jurisdiction, and his request for a COA is DENIED as MOOT.
