Bradford council has started its biggest fundraising campaign since the Valley Parade fire to help victims of the Pakistan floods.
The authority has already donated £20,000 to the Red Cross and has now started a public appeal for the Disasters Emergency Committee.
It comes as officials in Pakistan ask members of the United Nations to provide more financial aid.
Bradford's lord mayor said the city's residents had relatives affected.
Mayor Peter Hill said: "We have a large number of residents in Bradford with Pakistani origins and many of them have extended family caught up in this disaster so we have a particularly strong connection to what is happening.
"Our council has donated £20,000 and hopefully as a district we will be able to raise a considerable sum of money which will help to bring relief to as many people as possible."
Collection buckets will be placed across the district and also in council buildings.
The council started a fundraising campaign after a fire during a football match at Bradford City's Valley Parade stadium in 1985, in which 56 people died and more than 270 were injured.
