José "Pepín" Bello Lasierra (13 May 1904 – 11 January 2008) was a Spanish intellectual and writer.
His parents were friends of such Spanish intellectuals as Joaquin Costa, Santiago Ramón y Cajal, and Francisco Giner de los Rios.
At the age of eleven, he participated in the Madrid artist promotion "Residencia de Estudiantes de Madrid" where he met Salvador Dalí, Luis Buñuel, Federico García Lorca, and Rafael Alberti.
Even though some of his paintings, which he called "Artists Without Deeds", were published, he was known mainly as the organizer of art events.
He also managed a hydropower plant in the province of Huesca, operated a tannery in Burgos, and owned a drive-in theatre in Madrid.
