Kendrelle Brown, Louisiana prisoner # 526042, appeals the district court’s dismissal of his 28 U.S.C. § 2254 petition, *350 challenging his convictions and sentences for simple battery and armed robbery. The district court granted Brown a certifí-cate of appealability.

The timing of Brown’s notice of appeal (NOA) raises a threshold jurisdictional question that we address sua sponte. See Hernandez v. Thaler, 630 F.3d 420, 424 & n. 11 (5th Cir. 2011). A habeas proceeding is a civil action, so the “timely filing of a notice of appeal is a jurisdictional prerequisite.” Id. at 424. Brown had 30 days from the entry of the judgment on July 1, 2013, to file his NOA, see Fed. R.App. P. 4(a)(1)(A), so the NOA was due July 31, 2013, see Fed. R.App. P. 26(a)(1)(A), (B).

Brown did not file an NOA within the 30-day period. Instead, on September 3, 2013, he filed an NOA and a motion for an extension of time to file his NOA, claiming good cause under Rule 4(a)(5)(A) of the Federal Rules of Appellate Procedure. The problem for Brown, however, is that a Rule 4(a)(5) motion based on good cause or excusable neglect must be filed within 30 days of the expiration of the time to file an NOA. Fed. R.App. P. 4(a)(5)(A)(i). Because the period for filing an NOA expired on July 31, the motion for extension was due August 30. See Fed. R.App. P. 26(a)(1). The September 3 motion was therefore untimely. See, e.g., In re MDL 262, 799 F.2d 1076, 1078-79 (5th Cir. 1986) (holding that compliance with Rule 4(a)(5) is essential to appellate jurisdiction).

Because Brown failed to file a timely NOA, we do not have jurisdiction. See Hernandez, 630 F.3d at 424 & n. 11; In re MDL 262, 799 F.2d at 1078-79. The appeal, accordingly, is DISMISSED for want of appellate jurisdiction.
