Philipp Muntwiler (born 25 February 1987) is a Swiss professional football manager and a former player.

After a rather short loan commitment at FC Wil "Munti", as he is called by his fans, managed in the season 2005/06 under coach Ralf Loose the leap into the first team of FC St. Gallen and completed his first three appearances in the Super League.

Muntwiler came on in the scoreless game against FCZ about fifteen minutes before the end; In retrospect, the Swiss Football League Disciplinary Commission rated the match as a 3:0 -forfait victory for the Zürich team.

In the season 2007/08, Muntwiler made further progress and secured, then under Rolf Fringer, a regular place in the defensive midfield.

However, his involvement in St. Gallen did not detract from that; on the contrary: Muntwiler extended his contract prematurely in autumn 2008 for one year until 30 June 2010.
