This research describes solidarity of Mowgli’s Wolf Pack in Rudyard Kipling’s The Jungle Book. The objectives of this research are to describe the solidarity of Mowgli as a protagonist character and his wolf pack as supporting characters portrayed and to describe the role of the Law of the Jungle as the welfare of the jungle in the novel. This is a descriptive qualitative library research. The main data are words, phrases, sentences taken from The Jungle Book by Rudyard Kipling. The supporting data for this research are taken from articles, books, journals, critics and other academic writings. This research uses moral philosophical approach and act- and rule-utilitarianism theory. The final result shows that there are five fundamental things described in the solidarity between Mowgli and his Seeonee Wolf Pack: love, willing-sacrifice, trust, forgiveness and loyalty. The five foundations, called as the basics of solidarity, create a healthy relationship for every individual in the group. Besides, the role of the Law of the Jungle describes its role as a reminder tool to maintain the happiness of the social life. This means both, good actions and rules, are complementary. A good solidarity can unify different persons.
