Simeoni wa Mnarani Kijana (kwa Kiarabu مار سمعان العمودي الأصغر mār semʻān l-ʻamūdī l-asghar; Antiokia, leo nchini Uturuki, 521 - Antiokia, 24 Mei 592) alikuwa mkaapweke aliyepata umaarufu kwa kuishi miaka 68 juu ya minara mbalimbali akianzia utotoni kwa kufuata mfano wa Yohane, kiongozi wake wa kiroho. Alipohama mnara mmoja kwenda mwingine alipata nafasi ya kupewa ushemasi halafu upadri. Mbali na kutenda miujiza mingi, aliacha maandishi mbalimbali. Umeongezewa sifa "kijana" ili kumtofautisha na waliofuata mtindo wake huo kama Simeoni wa Mnarani Mzee, Simeoni wa Mnarani III na Simeoni wa Mnarani wa Lesbos. Tangu kale anaheshimiwa na Waorthodoksi, Waorthodoksi wa Mashariki, Wakatoliki na Waanglikana kama mtakatifu. Sikukuu yake huadhimishwa tarehe 24 Mei .
