The lantaka (Baybayin (pre virama): ᜎᜆᜃ; post virama: ᜎᜈ᜔ᜆᜃ), also known as the rentaka (Jawi: رنتاک), was a type of bronze portable cannon or swivel gun, sometimes mounted on merchant vessels and warships in Maritime Southeast Asia. It was commonly equipped by native seafaring vessels from the Philippines, Indonesia, Brunei, and Malaysia. Lela and rentaka are known by the Malays as meriam kecil (lit. 'small cannon'), the difference is that rentaka is smaller in length and bore than a lela. In Filipino, lantaka are often called kanyon (lit. 'cannon').
