Preheat your oven to 350°F and grease a 9x5-inch loaf pan.

In a large mixing bowl, whisk together the flour, sugar, baking powder, baking soda, and salt.

Add the orange juice, orange zest, oil, and beaten egg to the dry ingredients. Stir until just combined; do not overmix.

Fold in the chopped cranberries until they are evenly distributed throughout the batter.

Pour the batter into the prepared loaf pan and smooth the top with a spatula.

Bake in the preheated oven for 60 minutes, or until a toothpick inserted into the center of the bread comes out clean.

Allow the bread to cool in the pan for about 10 minutes, then remove from the pan and cool completely on a wire rack before slicing.
