  • @HiteshBalpande I tried that , it does not work – Nafsss Jan 9 at 6:54

You can try using category model:

Code for block file

protected $_categoryFactory;

public function __construct(
\Magento\Catalog\Model\CategoryFactory $categoryFactory,
) {
        $this->_categoryFactory = $categoryFactory;

public function getSubCatNameById($catId) {
        $categoryName = $this->_categoryFactory->create()->load($catId)->getName();
        return $categoryName;

Code for phtml file

$catId = 2;  //2 is your category id

echo $block->getSubCatNameById($catId);

Hope it will help you!

  • Does this return child category name? – Nafsss Jan 9 at 6:43
  • @Nafisa yes, by using this you can get the category name. – Faisal Sheikh Jan 9 at 6:47
  • Shiekh ......... In your code, no where it is mentioned about child category. your code will return parent category name. – Nafsss Jan 9 at 6:48
  • @Nafisa updated, you can check now. – Faisal Sheikh Jan 9 at 6:49
  • Have you tried this code? and checked what does it return? I want to use Parent category id to get child category name – Nafsss Jan 9 at 6:52

Please copy this code in your custom module block function, I hope it will be helpful for you.

   protected $categoryFactory;

   public function __construct(
        \Magento\Catalog\Model\CategoryFactory $categoryFactory
    ) {
        $this->categoryFactory = $categoryFactory;

    public function getSubCategories() {
        $_category = $this->categoryFactory->create();
        $catId = 12;    // your parent category name
        $category = $_category->load($catId);

        $collection = $category->getCollection()
        return $collection;   //Get subcategory collection of parent category


call above function in your phtml file like this:

    $subCategories= $block->getSubCategories();

    foreach($subCategories as $subCats):
            echo $subCats->getName();
