Hauméa (simbol: ),^[12] resmina katelah (136108) Hauméa atawa landihan saheulaanana (136108) 2003 EL61 nyaéta planet katé di beubeur Kuiper, ceuk itungan kasarna mah massana téh kira kira sapertiluna massa Pluto, kapanggih ku tim-na Mike Brown di Caltech di Amérika Sarikat atawa J. L. Ortiz et al. ti Instituto de Astrofísica de Andalucía di Obsérvatorium Sierra Nevada di Spanyol (keur disawalakeun kénéh). Ngan ari Minor Planet Center mah, netepkeun tim-na si Ortiz nu manggihna téh, ku sabab manéhna jelema anu mimiti ngabéwarakeun éta objek. Dina tanggal 17 Séptémber 2008, Hauméa diklasifikasikeun salaku planét katé ku IAU. Hauméa dikurilingan ku dua satelit alami anu dibéré ngaran Namaka jeung Hi'iaka, duanana mangrupa astéroid anu kakurung ku médan gravitasi Hauméa. Hauméa kaasup planet katé anu samanéa, ku sabab wangunna élips. Hauméa dikira-kira mibanda lega permukaan aya kana 2×10^7 km2 atawa 20,000,000 km2 anu hartina Hauméa mibanda lega permukaan anu saeutik leuwih badag tibatan Nagara Rusia.
