OPINION

Petitioner Frederick M. Torrence, a prisoner proceeding pro se, seeks a writ of mandamus compelling the District Court to order production of discovery materials. For the reasons that follow, we will deny the petition.

Torrence filed a complaint pursuant to 42 U.S.C. § 1983 against prison officials in the United States District Court for the Western District of Pennsylvania. Torrence has filed four motions requesting that the District Court order the production of allegedly discoverable information. The Court denied three such motions, and one remains pending. 1

*490 In his petition, Torrence alleges that the District Court arbitrarily denied his discovery motions and colluded with Defendants to deny Torrence a fair trial. He alleges that such actions violate his rights under the First and Fourteenth Amendments to the United States Constitution, and seeks a writ directing the District Court to order that Defendants produce the sought-after information.

Mandamus is an “extraordinary remedy” that we have discretion to award only when a petitioner demonstrates, among other things, a “clear and indisputable” right to relief. In re Pressman-Gutman Co., 459 F.3d 383, 398-99 (3d Cir. 2006). Mandamus lies only when there is no other remedy, Mallard v. U.S. Dist. Court for the S. Dist. of Iowa, 490 U.S. 296, 309, 109 S.Ct. 1814, 104 L.Ed.2d 318 (1989), and must not be used as a mere substitute for appeal. In re Diet Drugs Prods. Liab. Litig., 418 F.3d 372, 379 (3d Cir. 2005). Because Torrence’s petition amounts to an appeal of the District Court’s denial of his discovery motions, mandamus is not an appropriate remedy and we deny his petition. See Westinghouse Elec. Corp. v. Philippines, 951 F.2d 1414, 1422 (3d Cir. 1991).
