Motto	Negeri Kedah (State of Kedah)

The flag and coat of arms of Kedah are the state symbols of Kedah, Malaysia. Very little distinction is present between the flag and coat of arms of the state, as the flag consists of only a red field with the state arms on the upper hoist.

The Kedahan flag is essentially a red flag with only the state arms of Kedah charged on its upper hoist, the upper left quarter of the flag. The red, Kedah's traditional colour, signifies prosperity, while the flag's arms is as interpreted with the standalone arms.

Kedah's royalty flies a series of Royal Standards that consist of plain coloured flags with the state arms charged at the centre or flags with a canton of a different colour containing the state arms. In addition, similarly designed Standards are also flown by high-ranking governments officials affiliated with the Sultan of Kedah. Like the state flag, all Standards utillise any two of or all three colours: Red, green and yellow; the colours of the arms also vary between Standards.

The Standards include:

As a formerly independent state, Kedah was known to fly ensigns on its ships. Among them were the state ensign and civil ensign, the former similar in design as a variant of the Kedahan Standards, while the latter adopted a different design.

The state ensign took the appearance of a Standard-like design that simply incorporates a canton containing the state arms. The flag is blue, but unlike Standards of the design, its canton is essentially design as per the state flag, coloured red and containing the state arms in its original colours.
