Hallgrimskirkja is a Lutheran parish church in Reykjavik, Iceland. At 74.5 metres high, it is the largest church in Iceland and among the tallest structures in the country. The church is named after the Icelandic poet and clergyman Hallgrimur Petursson, author of the Passion Hymns.

It was designed by the late Guðjón Samúelsson
in 1937, who was often inspired in his endeavours by the fascinating shapes and forms created when lava cools into basalt rock.
Construction of the church began in 1945 and ended in 1986.

Standing directly in front of the church, and predating it by 15 years, is a fine statue of Leifur Eiríksson (c. 970 – c. 1020) – the first European to discover America.
