The so-called Grand Mac comes with two heftier all-beef patties, two slices of cheese, more lettuce and onions on a huge sesame bun for very hungry customers.
It will also set you back by nearly £4 and about 741kcal.
Kinder to your wallet and to your waistline, the Mac Jr is essentially just a single-patty burger with special sauce and is intended to be "easily eaten on the go".
You can pick it up for £2.19 and it has 400kcal - about a 100 less than a regular Big Mac, for customers who don't want to ruin their January diet.
Sadly, the new limited-edition burgers will be available until March 20 only - so you'll need to be quick if you want to try it.
