The royal couple will attend the highly anticipated clash at the Principality Stadium.
They will be supporting opposing teams in their official capacities as patrons of their respective rugby unions.
Kate's attendance means she will likely miss her niece Grace Matthews' fourth birthday celebrations.
Grace, daughter of Pippa Middleton and James Matthews, turns four today.
While the royal couple attends the rugby match, Grace will presumably celebrate with her siblings Arthur and Rose in Berkshire.
Prince William serves as Patron of the Welsh Rugby Union, cheering on Wales.
Meanwhile, Princess Catherine will support England as Patron of the Rugby Football Union and the Rugby Football League.
Before the match, the royal couple will meet injured players supported by the Welsh Rugby Charitable Trust.
This meeting will take place in the Sir Tasker Watkins Suite, a dedicated space at the Stadium for injured players and their families.
Prince William serves as Patron of this important organisation.
The Welsh Rugby Charitable Trust was established in 1972 with various education, social and sporting objectives.
LATEST ROYAL NEWS:
While the charity has multiple aims, its principal focus has always been supporting players and their families who have been severely injured whilst playing rugby in Wales.
The charity ensures all injured players are invited to every Wales home game.
Each year, the Welsh Rugby Union hosts a special "Family Day" event.
This annual gathering allows injured players to enjoy quality time together with their families.
