The 2021 London Marathon was the 41st running of the annual London Marathon on 3 October 2021. Due to the COVID-19 pandemic, the race was postponed from April until October to maximise the chances of a mass participation event.

The elite events were won by Sisay Lemma of Ethiopia and Joyciline Jepkosgei of Kenya, in 2:04:01 and 2:17:43, respectively. The wheelchair races were won by Marcel Hug and Manuela Schär, both of Switzerland, in 1:26:27 and 1:39:52, respectively. Both Hug and Schär set course records, with Hug breaking Australian Kurt Fearnley's record of 1:28:57 set in 2009, and Schär breaking her own record of 1:39:57 set in 2017. Around 40,000 competed in the mass participation event, with an additional 40,000 people partaking in the virtual marathon.
