Chup Tazia is a religious procession held mostly on the 8th of Rabi al-awwal by Twelver Shia Muslims in India and Pakistan to commemorate the death of Imam Hasan al-Askari, the eleventh of the Twelver Shia Imams. The procession is also known as the silent tazia because it is held in silence, without any music or chanting.

The Chup Tazia procession originated in the Indian city of Lucknow during the nawabi era and was started by Nawab Ahmed Ali Khan Shaukat Yar Jung, a descendant of Bahu Begum. It is one of the most important processions of azadari in Lucknow and is currently one of the nine allowed processions. The tradition quickly spread to other parts of South Asia, including Pakistan, after the independence of Pakistan in 1947.

The Tazia is a replica of the mausoleum of Imam Hussain, the Prophet Muhammads grandson, and is a significant component in Muslim celebrations of the month of Muharram. Taziyat, which implies expressing sympathy, reverence, and respect for the deceased, derives from the Arabic term aza, which means to remember the deceased.

The Chup Tazia procession is held in silence to show respect for the deceased and to mourn the loss of Imam Hasan al-Askari. The procession is taken out in various cities in India and Pakistan, including Lucknow, Hyderabad, Kanpur, Bhopal, Delhi, Amroha, Jaunpur, and Karachi.

In Karachi, there are two Chup Tazia processions. The first procession starts after the Fajr prayer from Nishtar Park in Soldier Bazar and culminates at Imambargah Hussainia Irania in Kharadar after the Zohrain prayers. The second procession originates from Qasr-e-Musayyab in Rizvia Society and culminates at Imambargah Shah-e-Najaf on Martin Road.
