Iyengar Yoga (UK) is the official organisation for Iyengar yoga in the United Kingdom and Republic of Ireland. It introduces people of all ages, abilities, health conditions and body types to this method, developed by the late B.K.S. Iyengar and rooted in Indian yoga philosophy. The organisation helps people explore the practice and connect with certified teachers, local classes, groups and centres through its searchable directory.

Iyengar Yoga (UK) also shares information about teacher training, Iyengar yoga therapy and study at the Pune Institute. Its events programme includes workshops, holidays, retreats and conventions, while online resources feature articles, research, videos, podcasts and news about the tradition. The organisation supports a community of members, who receive regular updates, a biannual magazine, equipment discounts and invitations to conventions and online events. Through its website and regional network, Iyengar Yoga (UK) provides guidance for newcomers and ongoing opportunities for students and teachers to learn, practise and engage with the wider Iyengar yoga community.
