Byron Bernard Dupree, Texas inmate #828005, moves pro se for leave to proceed in forma pauperis (IFP) in his appeal of the dismissal of his 42 U.S.C. § 1983 complaint as frivolous. Dupree’s IFP motion is a challenge to the district court’s certification that his appeal was not taken in good faith. See Baugh v. Taylor, 117 F.3d 197, 202 (5th Cir. 1997). In his complaint, Dupree alleged that the National Association for the Advancement of Colored People (NAACP) and its president, *368 Kwesi Mfume, violated his civil rights by refusing to provide him with legal representation to challenge his conviction and resulting incarceration on a drug charge.

This court reviews the dismissal of a complaint as frivolous for abuse of discretion. Taylor v. Johnson, 257 F.3d 470, 472 (5th Cir. 2001). A complaint is frivolous if it lacks “an arguable basis in law or fact”. Berry v. Brady, 192 F.3d 504, 507 (5th Cir. 1999). The district court did not err in dismissing Dupree’s complaint. Neither the NAACP, a private organization, nor Mfume, a private citizen, is a state actor. Rendell-Baker v. Kohn, 457 U.S. 830, 838, 102 S.Ct. 2764, 73 L.Ed.2d 418 (1982); Yeager v. City of McGregor, 980 F.2d 337, 339 (5th Cir.), cert. denied, 510 U.S. 821, 114 S.Ct. 79, 126 L.Ed.2d 47 (1993).

Dupree’s appeal lacks arguable merit, and the district court did not err in finding it was not taken in good faith. See Howard v. King, 707 F.2d 215, 219-20 (5th Cir. 1983). Accordingly, Dupree’s motion for leave to proceed IFP on appeal is DENIED, and his appeal is DISMISSED as frivolous. See Baugh, 117 F.3d at 202 n. 24; 5th Cir. R. 42.2. The dismissal of Dupree’s appeal as frivolous counts as a “strike” for the purposes of 28 U.S.C. § 1915(g), as does the district court’s dismissal as frivolous of his 42 U.S.C. § 1983 complaint. See Adepegba v. Hammons, 103 F.3d 383, 387 (5th Cir. 1996). We CAUTION Dupree that once he accumulates three strikes, he may not proceed IFP in any civil action or appeal filed while he is incarcerated or detained in any facility unless he is under imminent danger of serious physical injury. See 28 U.S.C. § 1915(g).
