A meal delivery service is a service that sends customers fresh, frozen, or hot prepared meals delivered to their homes and offices. These services individually package pre-portioned meals to assist with eating a healthy meal. These services cook and prepare meals for customers. Meals may come in small Tupperware containers.

Meal delivery orders are typically on-demand, intended to be eaten right away, and include hot, already-prepared food. While some service providers offer subscription services, ordering for delivery usually involves contacting a local restaurant or chain by telephone or online.

Meal delivery requires special technology and care, since the food items are already cooked and prepared, and can be easily damaged if dropped, tilted, or left out for long periods of time. Hot bags are often used to keep food warm. They are thermal bags, typically made of vinyl, nylon, or Cordura, that passively retain heat.
