11 Camelopardalis (11 Cam / HD 32343 / HR 1622)^[11] ye una estrella na constelación de Camelopardalis, la xirafa, de magnitú aparente +5,03. Constitúi una estrella doble con 12 Camelopardalis, de la que ta dixebrada 3 minutos d'arcu. Alcuéntrase aproximao a 670 años lluz del Sistema Solar.

Coordenaes: 5^h 6^m 8.453^s, 58^° 58^′ 20.543^″

11 Camelopardalis ye una estrella blancu-azulada de tipu espectral B2.5Ve con una temperatura efectivo de 16.121 K.^[12] Tien un radiu 4,5 vegaes más grande que'l del Sol. La so masa envalórase en 5 mases solares y tien una edá averada de 55 millones d'años.^[13]

La rápida rotación de 11 Camelopardalis —la so velocidá de rotación proyeutada ye de 102 km/s^[12]— favorez que seya una estrella Be; nestes estrelles esiste un discu circunestelar qu'emite radiación, creáu pola perda de masa dende les zones ecuatoriales de la estrella. Achernar (α Eridani) o α Arae son dos estrelles Be asemeyaes a 11 Camelopardalis. Esta postrera apaez catalogada como variable eruptiva Gamma Cassiopeiae, recibiendo la denominación de variable BV Camelopardalis.^[14]
