Pablo Guillermo Wagner San Martín (June 29, 1970) is a Chilean commercial engineer, businessman, and politician.

After a long period in the private sector, he was Undersecretary of Mining in the first government of President Sebastián Piñera between 2010 and 2012.

He developed a close relationship with businessman Carlos Alberto Délano, one of the group's main shareholders.

[2] In 2010, after Sebastián Piñera's victory in the 2009–2010 presidential election, he was appointed as the Undersecretary of Mining, with Laurence Golborne serving as the Minister.

This was due to the non-compliance of the winning company, Sociedad Química y Minera de Chile (SQM), with the terms and conditions.
