Henry Manni (born 18 June 1992) is a Finnish athlete and paracanoeist who has competed and medaled in both fields at World Championship level.

[3] Manni was inspired to take up disability sport in 2004 after watching Finland's Leo-Pekka Tahti win gold at the Summer Paralympics in Athens.

In 2010 he achieved his best paracanoe result when he won a bronze medal in the K-1 200 m TA event at the 2010 ICF Canoe Sprint World Championships in Poznań, Poland.

Without the competition of international athletes such as Tunisia's Walid Ktila and Australia's Rheed McCracken, Manni dominated the field winning four gold medals in all four sprint events.

[1] In the build up to the 2016 Summer Paralympics in Rio, Manni again represented Finland in the IPC World Championships, this time in Doha.
