The 20 Party Alliance was a Bangladeshi big tent political coalition led by the Bangladesh Nationalist Party (BNP). It was originally formed as the 18 Party Alliance on 18 April 2012 in Dhaka, extending its predecessor the 4 Party Alliance. The Alliance was formed in an effort to strengthen the opposition's demands for restoring the caretaker government system used between 1996 and 2008. The main rival of this coalition was the Grand Alliance, led by Awami League, which came into power after the election in 2008. The 20 Party Alliance was dissolved on 09 December 2022.
