The National Democratic Convention (Nadeco) was a South African political party formed in August 2005 via floor crossing legislation[1] by Ziba Jiyane, the former Inkatha Freedom Party (IFP) chairperson.

[2] In September 2005 the provincial African Christian Democratic Party leader and MP Reverend Hawu Mbatha joined Nadeco.

Jiyane was suspended by the IFP leadership and resigned, forming Nadeco.

After a protracted legal dispute with Mbatha, he formally split from the party in December 2007 and retired temporarily from politics, later forming the South African Democratic Congress in 2008.

Nadeco lost all of its national and provincial seats in the 2009 general election and subsequently disbanded.
