The national flag of Belarus is a red-and-green flag with a white-and-red ornament pattern placed at the hoist (staff) end. The current design was introduced in 2012 by the State Committee for Standardisation of the Republic of Belarus, and is adapted from a design approved in a May 1995 referendum. It is a modification of the 1951 flag used while the country was a republic of the Soviet Union. Changes made to the Soviet-era flag were the removal of communist symbols – the hammer and sickle and the red star – as well as the reversal of the colours in the ornament pattern. Since the 1995 referendum, several flags used by Belarusian government officials and agencies have been modelled on this national flag.

A jack is a flag flown from a short jackstaff at the bow (front) of a vessel, while the ensign is flown on the stern (rear). Jacks on bowsprits or foremasts appeared in the 17th century. A country may have different jacks for different purposes, especially when the naval jack is forbidden to other vessels. The United Kingdom has an official civil jack; the Netherlands has several unofficial ones. In some countries, ships of other government institutions may fly the naval jack, e.g. the ships of the United States Coast Guard and the National Oceanic and Atmospheric Administration in the case of the US jack. Certain organs of the UK's government have their own departmental jacks. Commercial or pleasure craft may fly the flag of an administrative division or municipality at the bow. Merchant ships may fly a house flag. Yachts may fly a club burgee or officer's flag or the owner's private signal at the bow. Practice may be regulated by law, custom, or personal judgment.
