Jean-Claude Nicolas Forestier (9 January 1861 – 26 October 1930) was a French landscape architect who trained with Adolphe Alphand and became conservator of the promenades of Paris.

Forestier also worked in Spain, setting up gardens in Seville including the Maria Luisa Park (1914) which showcased botanicals, French geometry and Latin and Islamic design and decoration.

Forestier also worked in private commissions, such as the Palacio de Liria (1916) in Madrid and the gardens of La Casa del Rey Moro in Ronda.

Forestier's Haussmanian tradition and tendencies towards monumentality were popular with cities looking to represent ideas of nationalism in their design.

The scholar Vincent Casals Costa argues that Forestier's practical model of urban design is that of a "city-park."
