Sebastián Vidal y Soler (Barcelona, April 1, 1842 – Manila, July 28, 1889) was a Spanish forester and botanist.

Sebastián Vidal and his lesser known brother, Domingo, studied at the Spanish forestry school.

Sebastián Vidal had a particular interest in woody plants, but studied Malesian flora in general, collecting specimens, collaborating with other botanists, and publishing a number of works including Revision de Plantas Vasculares Filipinas (Manila 1886).

Plants were exhibited at the newly constructed Palacio de Cristal in the Retiro Park.

Although the herbarium in Manila was destroyed in a fire in 1897, some of Vidal's specimens of Philippine flora are preserved in Europe to this day, at Kew,[6] where he collaborated with Robert Allen Rolfe, and at Madrid's Real Jardín Botánico, where, since Vidal's death Benjamín Máximo Laguna and later scholars have worked on them.
