János Kóka (born 5 July 1972) is a Hungarian businessman, private investor, IT entrepreneur and manager of various enterprises, who served as Minister of Economy and Transport between 2004 and 2007.

[citation needed] Kóka got involved in the emerging Hungarian IT industry while still at university, working as Project Manager and later Sales Director at one of Hungary's first ISPs, Elender LLC from 1994 and 1996.

From 2003 prior to his ministerial appointment he served as Member of the Board of EICTA (European ICT Association) based in Brussels, and Chairman of the Hungarian-Indonesian Joint Business Council.

During this period his main tasks included the development of a business-friendly environment, stimulating the growth of the corporate sector, promoting a knowledge-based economy and increasing the international presence of domestic businesses.

His popularity began to drop in 2006[2] following the announcement of his Ministry's intention to shut down 14 regional lines of Hungarian State Railways on a total length of 474 km (295 mi).

However, the legitimacy of Kóka's position as party president became questioned when it was discovered that some signatures of the delegates to the assembly electing him had been forged.

Under his management, the company has reported the conclusion of several international agreements of cooperation; for instance, Cellum developed the mobile payment application of MasterCard.
