Louis-Philippe de Grandpré CC GOQ QC AdE (February 6, 1917 – January 24, 2008) was a Canadian lawyer and puisne justice of the Supreme Court of Canada.

He was the subject of controversy that year when objections were raised to him hearing the case Morgentaler v. The Queen given his prior personal statements about the issue at a 1973 national meeting of the Canadian Bar Association.

In the end, the Chief Justice decided that de Grandpré could remain on the panel to hear the abortion case.

[5] By October 1, 1977, de Grandpré resigned complaining of Chief Justice Bora Laskin's style of running the Court and the direction it was taking on many constitutional matters.

The funeral service was held at Saint-Viateur d'Outremont and he was entombed at the Notre Dame des Neiges Cemetery in Montreal.
