Mariano Benlliure y Gil (8 September 1862 – 9 November 1947) was a Spanish sculptor and medallist, who executed many public monuments and religious sculptures in Spain, working in a heroic realist style.

At the age of thirteen he showed a wax modello of a picador at the Exposición Nacional de Bellas Artes, 1876.

In 1887 he established himself permanently in Madrid, where in that year's Exposición Nacional his portrait sculpture of the painter Ribera won him a first-prize.

His portrait busts and public monuments are numerous, and include: Benlliure was the protector of the Cadiz sculptor Juan Luis Vassallo, taking charge of the reproduction of the work La Jeroma, which in 1927 had won first prize at the Casino.
