Siti Nurbaya Bakar (born 28 July 1956) is the Minister of Environment and Forestry in Indonesian President Joko Widodo's Working Cabinet.

After graduating from college, she started work in 1981 for the Regional Development Planning Board (Bappeda) in Lampung and remained there for 17 years.

She was alleged to have received Rp 100 million in a fire truck procurement deal when she was the secretary general at the Home Affairs Ministry, but she was not pursued by the Corruption Eradication Commission (KPK) because she said the project had involved the minister and the ministry's director general without going through her.

[4] She was appointed by president Susilo Bambang Yudhoyono as secretary general of the Regional Representatives Council (DPD) for 2006–2013.

[5] In January 2013, Siti stepped down from the DPD and joined media tycoon Surya Paloh’s National Democrat Party.
