Algarkirk (/ˈældʒərkɜːrk/ AL-jər-kurk) is a village and civil parish in the Borough of Boston in Lincolnshire, England.

[3] Algarkirk has been claimed to be named after Ælfgar, Earl of Mercia, a son of Lady Godiva;[4] he is reputedly buried in the graveyard[5] of the parish church of St Peter and St Paul.

[6] The 9th-century church itself is Early English and Norman with a double-aisle transept and a font of Purbeck marble.

Under the tower are kneeling brass effigies of Nicholas Robertson (d. 1498), Merchant of the Staple of Calais, and his two wives Alice and Isabella.

[2] The village was once served by Algarkirk and Sutterton railway station on the now-closed line connecting Boston and Spalding.
