Ensign vs. Flag — What's the Difference?
By Fiza Rafique & Maham Liaqat — Updated on May 13, 2024
An ensign is a specific type of flag used primarily to denote nationality on ships and aircraft, often with special symbols to indicate civil, state, or naval service. A flag, however, is a broader term that includes any symbolic banner used for identity.

Key Differences
An ensign is used specifically in maritime and aeronautical contexts to show a ship's or aircraft's nationality and sometimes its service type, such as navy or coast guard. In contrast, a flag can represent a country, organization, team, or even individual ideas and can be used in a wide range of settings from governmental buildings to sports events.
While all ensigns are flags, not all flags are ensigns. Ensigns serve a regulatory and formal purpose to identify vessels on international and domestic waters, whereas flags might be used for decoration, signaling, or to convey broader messages.
There are specific regulations regarding the design, size, and use of ensigns, particularly in naval and civil contexts, ensuring that ships and aircraft are correctly identified according to international laws. Flags, however, can vary greatly in design and usage based on cultural, national, or individual preferences.
The design of an ensign often includes elements from a national flag but might also incorporate specific symbols or alterations to distinguish between different types of services or levels of authority. General flags may not adhere to such standardized specifications and are often designed with more artistic freedom.
Ensigns are a vital part of naval and maritime tradition, strictly used and raised according to naval protocol. Flags might not always have such strict rules around their usage and can be more versatile in both private and public contexts.
