Fiancé Albritton, Texas prisoner # 1227150, appeals following the dismissal of his complaint brought under 42 U.S.C. § 1983 and the Americans with Disabilities Act and the court’s subsequent ruling that he had failed to file a timely notice of appeal. Albritton challenges only the court’s underlying judgment dismissing his complaint as frivolous. He does not challenge the court’s postjudgment order in which it rejected his claim that he had filed a notice of appeal on March 14, 2009.
For civil appeals, “[t]he filing of a timely notice of appeal, within thirty days after entry of the court’s judgment, is mandatory and jurisdictional.” Kinsley v. Lakeview Reg’l Med. Ctr. LLC, 570 F.3d 586, 588 (5th Cir.2009). Because the record does not reveal a timely notice of appeal from the underlying judgment, this court lacks jurisdiction to review Albritton’s argument. See id. Although we have juris*354diction to review the court’s subsequent postjudgment order, Albritton has failed to brief any argument challenging the order and, therefore, has abandoned the only cognizable claim on appeal. See Brinkmann v. Dall. Cnty. Deputy Sheriff Abner, 813 F.2d 744, 748 (5th Cir.1987).
APPEAL DISMISSED.
