Hamengkubuwono (also spelt Hamengkubuwana and in Dutch transcription "Hamengkoeboewono") is the current ruling royal house of the Yogyakarta Sultanate in the Yogyakarta Special Region of Indonesia. The current Sultan is Hamengkubuwono X.
As with many significant historical and respected figures in Javanese culture, the name of a ruler is usually preceded by honorifics – in most cases the usage is of Sri Sultan before the name. In full titles the first Hamengkubuwono was titled:
"Ngarsadalem Sampeyandalem Hingkang Sinuhun Kangjeng Sultan Hamengkubuwono, Senopati Ing Ngalaga Ngabdurrahman Sayidin Panatagama Kalifatulah, Hingkang Jumeneng Kaping I".
The Hamengkubuwono is considered by Javanese as the true claimant and heir to the throne of the Second Mataram Kingdom and the vast Majapahit Empire, hence the post-Independence special privileges of self-rule solely allotted to the Hamengkubuwana keraton (palace)- not extended to the other three princedoms and fiefdoms of the Treaty of Giyanti (1755)
For some Javanese, the name has been interpreted as having the following components:
- Hamangku: pleased to serve the people
- Hamengku: protect the people in a just way
- Hamengkoni: ready to take responsibility of a leader
- Buwono: the Javanese universe 
Such an explanation does not necessarily coincide with strict etymology of the word.
