Flag and coat of arms of Negeri Sembilan
The flag and the coat of arms of Negeri Sembilan are state symbols of Negeri Sembilan, Malaysia. Influenced by the heritage of the Minangkabau people, the original settlers in present-day Negeri Sembilan, the symbols are predominantly depicted in red, black and yellow, traditional colours of the Minangkabau. Also recognised in the symbols are the political history of Negeri Sembilan, its ruler, and the state's past relationship with the British Empire.
The flag of Negeri Sembilan consists of a yellow flag with a canton on the upper hoist, which is divided diagonally from the corner of the upper hoist towards the corner of the lower fly. The upper portion of the canton is coloured red, while the lower portion is coloured black, exactly like the flag of Papua New Guinea.
The symbolisation of the flag is primarily concentrated towards the association of the its colours with the people of the state. The yellow represents the Yang di-Pertuan Besar of Negeri Sembilan, the red denotes the citizens of the state, and the black symbolises the four undangs (traditional chiefs).
As well as being the state flag of Negeri Sembilan, the flag is also in use by the Yang di-Pertuan Besar as the royal standard to date. Prior to 1942, the British Resident of Negeri Sembilan was also assigned the same flag, with the exception it is forked at the fly.
Certain districts (luak) in Negeri Sembilan have their own flag for ceremonial uses during Adat Perpatih events. They are hardly seen in daily government administrative functions.

Coat of arms
The Negeri Sembilan coat of arms and state emblem is based on Western heraldry, but consists of only two heraldic elements: The shield (escutcheon) and crest or helm; the motto of the Negeri Sembilan arms, normally included on the bottom as a scroll on the majority of Malaysia's coats of arms, is embedded into the shield of the arms. Like the flag, the Negeri Sembilan coat of arms uttilises the colours black, red and yellow with the minor addition of white.
- The escutcheon of the arms is depicted as an Old French shield outlined in black and white. The shield itself is coloured in shades of the Minangkabau people's traditional colours, like the flag, but is illustrated in the form of three partitions separated by diagonal lines running from the upper left to the lower right and varies slightly by its symbolisation. The colours signify the following:
- Further adorning the shield are nine yellow stalks of rice attached to the motto in the form a white scroll with "Negeri Sembilan" written in Jawi scripture (نڬري سمبيلن), with a nine-pointed star below. The stalks signifies the nine states under the old Negeri Sembilan: Jelai (Inas), Jelebu, Johol, Kelang, Nanaing, Rembau, Segamat and Pasir Besar, Sungei Ujong, and Ulu Pahan. Similarly, the nine-pointed star symbolise the nine (original) states of Negeri Sembilan united as one.
- Crest or helm
- The shield is topped by a crest or helm in the form of a white staff known as the Changgai Putri (or Changgai Puteri), which is fronted by a red sword and red scabbard. The staff represents the Yang Di-Pertuan Besar, while the sword and scabbard signify justice. Additionally, the staff and sword represent the Yang di-Pertuan Besar's personal Sceptre of Regalia since 1948.
