Kōchikai (宏池会; "Masyarakat Kolam Luas") adalah sebuah faksi terkemuka dalam Partai Demokrat Liberal (LDP) Jepang, yang didirikan oleh Hayato Ikeda, seorang birokrat yang kemudian menjadi politisi, pada tahun 1957. Faksi ini telah menghasilkan lima perdana menteri (Ikeda, Masayoshi Ōhira, Zenkō Suzuki, Kiichi Miyazawa, dan Fumio Kishida), dua presiden LDP (Yōhei Kōno dan Sadakazu Tanigaki), dan sejumlah besar pejabat kabinet. Faksi ini resmi dibubarkan pada 23 Januari 2024 setelah Perdana Menteri Fumio Kishida berjanji untuk membubarkan faksi tersebut setelah skandal dana politik.^[6][7] Namun, mantan anggota partai masih berkumpul secara rutin dan menekan politikus lain secara kolektif.^[8]
