Tiffany Woods, Louisiana prisoner # 545546, was convicted of the second-degree murder of her five-month-old child and sentenced to a mandatory term of life. On November 9, 2015, she filed a motion for leave to file a Federal Rule of Civil Procedure 60(b) motion seeking relief from the dismissal of her 28 U.S.C. § 2254 application. The district court denied the motion for leave to file and Woods’s request for Rule 60(b) relief. Woods moves for a certificate of appealability (“COA”) to appeal the denial of her proposed Rule 60(b) motion.

A COA is required to appeal the denial of a Rule 60(b) motion except where the motion seeks to reinstate appellate jurisdiction over the initial denial of habeas corpus relief. Ochoa Canales v. Quarterman, 507 F.3d 884, 888 (5th Cir. 2007). A COA is also required to appeal the denial of an unauthorized successive § 2254 application. Cardenas v. Thaler, 651 F.3d 442, 443 (5th Cir. 2011).

The district court did not determine whether Woods was entitled to a COA. Because of that, we assume, without deciding, that we lack jurisdiction over the appeal. See Rule 11(a), Rules Governing § 2254 Cases; Cardenas, 651 F.3d at 444 & nn.1-2. Nevertheless, we decline to remand for a ruling on a COA, because a remand would be futile. See United States *264 v. Alvarez, 210 F.3d 309, 310 (5th Cir. 2000). Woods’s proposed Rule 60(b) motion was an unauthorized successive § 2254 application. See Gonzalez v. Crosby, 545 U.S. 524, 531-32, 125 S.Ct. 2641, 162 L.Ed.2d 480 (2005). Because the district court lacked jurisdiction to consider it, we lack jurisdiction to review the denial of Woods’s proposed Rule 60(b) motion on the merits. See United States v. Key, 205 F.3d 773, 774-75 (5th Cir. 2000).

Accordingly, the appeal is DISMISSED for want of jurisdiction, and the motion for a COA is DENIED as moot.
