Preheat oven to 350°F (175°C). Grease a loaf pan.
In a large bowl, cream butter and sugar until light and fluffy.
Add eggs one at a time, beating well after each addition.
Stir in vanilla extract and crushed pineapple.
In another bowl, whisk together flour, baking soda, and salt.
Gradually add dry ingredients to the wet mixture, mixing just until combined.
Pour batter into the prepared loaf pan.
Bake for 1 hour or until a toothpick inserted into the center comes out clean.
Let cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
