Ignisious Gaisah (born 20 July 1983) is a Ghanaian-born athlete competing in the long jump for the Netherlands.

In 2005 jumped a personal best 8.34 metres to win the silver medal at the World Championships in Helsinki, finishing behind Dwight Phillips.

On 2 February 2006, in Stockholm he leaped to an African indoor record that also won him the gold medal in this event by jumping 8.36 metres.

At the 2006 African Championships in Athletics Gaisah won the gold medal with an 8.51 m jump, beating Cheikh Touré's African record of 8.46 metres from 1997, but as the tail wind was too strong (+3.7 m/s) the result could not become a new record.
