Jacob Gabe "Jack" de Vries (born 25 July 1968) is a retired Dutch politician of the Christian Democratic Appeal (CDA) party and political consultant.

De Vries studied at the VU University Amsterdam where he in 1992 obtained a MSc degree in political science.

He was leader of the Christian Democratic youth movement (CDJA) and completed his military service with a stint as communications advisor to the Dutch Army.

Never away from national politics, he became media spokesman of the CDA parliamentary faction in 1997, serving under Enneüs Heerma and Jaap de Hoop Scheffer.

Balkenende won the 2002 elections, became Prime Minister, and brought de Vries with him to the Ministry of General Affairs.
