The celestial event took place just before sunset on April 27 as the moon rose in the east and will be visible until it sets in the west the next morning.
Photographs of the stunning lunar event showed the exceptionally bright moon casting its light over the capital.
Many took to social media to share their images of the supermoon rising over the city.
“Here’s the #Supermoon rising over South London. Lots of low cloud cover but still beautiful,” one tweeted.
Another wrote: “Supermoon over London. Not a single moment goes by where I don’t think about how lucky I am to be in such a spectacular part of the planet that I love so much.”
It could also be seen across other parts of the UK, with it spotted in Glastonbury and Amesbury.
The moon is also visible in clear skies over Venezuela, New Zealand, Germany, France and Spain.
According to Nasa, the term “supermoon” was coined by astrologer Richard Nolle in 1979, and refers to when the full moon is near its closest point to the Earth in its orbit.
Anna Ross, an astronomer at the Royal Observatory in Greenwich, said: "A supermoon is the result of a full moon occurring when the moon is near its closest point to the Earth in its orbit.
"This can happen because the moon orbits the Earth on an elliptical path, rather than a circular one.
"As this means that the moon is a little closer to us, it appears slightly bigger in the sky."
The full moon in April is also known as the "pink moon" because it is named after pink flowers, known as phlox, which bloom in the springtime.
The next supermoon will be visible in May.
