Sir Galahad (/ˈɡæləhæd/; yang terkadang disebut sebagai Galeas /ɡəˈliːəs/ atau Galath /ˈɡæləθ/), dalam legenda Arthur, adalah seorang kesatria Meja Bundar Raja Arthur dan salah satu dari tiga peraih Piala Suci. Ia adalah anak kandung dari pasangan Sir Lancelot dan Elaine dari Corbenic, dan dikenal karena keberanian dan kemurniannya. Dalam tradisi Arthur abad pertengahan, Sir Galahad mula-mula muncul dalam lingkar Lancelot–Grail, dan kisahnya dituangkan dalam karya-karya pada masa berikutnya seperti Post-Vulgate Cycle dan Le Morte d'Arthur karya Sir Thomas Malory.
