Francisco "Paco" Jémez Martín (born 18 April 1970) is a Spanish football manager and former player who played as a central defender.

During his career he played for Córdoba CF, Real Murcia, Rayo Vallecano (first appearing in La Liga and playing all 38 matches of the season), Deportivo de La Coruña (only totalling ten games in his first two seasons as the club achieved two consecutive runner-up spots, being more used afterwards) and Real Zaragoza,[1] which he helped to the 2001 conquest of the Copa del Rey.

His debut was on 23 September 1998 in a friendly against Russia in Granada,[4] and he was a participant at UEFA Euro 2000, taking part in three matches in an eventual quarter-final exit.

On 12 April 2010, following Sergije Krešić's dismissal, Jémez was appointed coach at struggling UD Las Palmas in division two.

[22] He rejoined Rayo Vallecano in late March 2019, replacing Míchel who had been dismissed two days earlier after losing seven league games in a row, which left the team at risk of top-flight relegation, and agreeing to a deal until June 2020.

[27] Jémez's father, Francisco Crespo Aguilar (known professionally as Lucas de Écija (1929–2018)), was a flamenco singer who released two records.
