Andrew "Sandy" Comyn Irvine (8 April 1902 – 8 June 1924) was an English mountaineer who took part in the 1924 British Everest Expedition, the third British expedition to the world's highest (8,848 m) mountain, Mount Everest.

While attempting the first ascent of Mount Everest, he and his climbing partner George Mallory disappeared somewhere high on the mountain's northeast ridge. The pair were last sighted only a few hundred metres from the summit. Mallory's body was subsequently found in 1999, but Irvine's body has never been found.
