Walter Maria de Silva (born 27 February 1951) is an Italian car designer and former head of Volkswagen Group Design, until 2015. Since beginning his car design career in 1972 as trainee car designer for Fiat's Style Centre, De Silva has also worked as a designer at I.DE.A Institute, and as head of design for Alfa Romeo, SEAT and the 'Audi brand group'. He is presently President of the Design Studio Walter De Silva Automotive.

De Silva was born in Lecco, near Milan, Italy. He was an avid sketcher starting from young age. His father Emilio was a graphic designer working as an executive for Fiat's marketing department. De Silva graduated from the Royal College of Art with a degree in automotive design.

Walter de Silva began his career in 1972 at age 21, working for Centro Stile Fiat.

After his experience at Fiat, Walter de Silva worked at Rodolfo Bonetto on designing automotive interior. In 1977 he began working at the I.DE.A Institute in Turin, Italy, continuing for nine years under the direction of Franco Mantegazza and Renzo Piano and eventually becoming a director at I.DE.A.

In 1986 Walter de Silva was recruited away from the I.DE.A. Institute to become head of Centro Stile Alfa Romeo. Walter de Silva remained in this role until 1999.

At Alfa Romeo, de Silva led the renewal of the brand's design language and repositioning.

In 1999 Ferdinand Piëch assigned Walter de Silva to work for the Volkswagen Group SEAT division, with the aim of injecting verve and sportiness to SEAT design. The result was SEAT 'auto emoción' philosophy which was first demonstrated in the 2000 SEAT Salsa and the 2001 SEAT Tango concept cars, as a foretaste of SEAT new design language, with the latter receiving in 2002 the 'Autonis Award' in the Concept Car category. His more expressive design approach has since influenced the form and look of numerous cars, such as the 2002 SEAT Córdoba and SEAT Ibiza, as well as the 2004 SEAT Altea and 2005 SEAT León which were highly acclaimed and subsequently received several design awards (e.g. Red dot design award, Autonis award, 'The World's Most Beautiful Automobile 2004' award in Milan, etc.). During his time at SEAT, de Silva was approached by Volkswagen head of design Hartmut Warkuß, and commissioned to submit a new Bugatti design for the upcoming revival of the brand. De Silva's design was rejected in favour of Warkuß's own design, which would later become the Bugatti Veyron.

In March 2002 Walter de Silva was appointed Head of Design to the now-defunct Audi brand group which encompassed the Audi, SEAT and Lamborghini brands. Volkswagen Group management charged de Silva with giving the Audi range a more emotional design language which included the controversial introduction of the full-height, single-frame front grille that now adorns all Audi models. His first full design for a production Audi was the 2005 A6. He has since gone on to contribute to the 2005 Audi Q7, 2006 Audi TT and the 2007 Audi A5, which he called 'the most beautiful car he ever designed.'
