As ‘clothing’ is an example in the snippet below, be sure to use a product category slug that exists in your WooCommerce store.

Note that this will only work when you have your “Shop Page Display” option set to ‘Show Products’ under your Customizers’ WooCommerce > Product catalog settings.

Add this code to your child theme’s functions.php file or via a plugin that allows custom functions to be added, such as the Dessky Snippets plugin. Please don’t add custom code directly to your parent theme’s functions.php file as this will be overwritten completely when you update the theme.

/**
 * Exclude products from a particular category on the shop page
 */
function custom_pre_get_posts_query( $q ) {

    $tax_query = (array) $q->get( 'tax_query' );

    $tax_query[] = array(
           'taxonomy' => 'product_cat',
           'field' => 'slug',
           'terms' => array( 'clothing' ), // Don't display products in the clothing category on the shop page.
           'operator' => 'NOT IN'
    );


    $q->set( 'tax_query', $tax_query );

}
add_action( 'woocommerce_product_query', 'custom_pre_get_posts_query' );
