The Tube drivers' strike was announced after Aslef members voted by 9-1 in favour of strikes in a long-running row over extra pay for working on Bank Holidays.
The ballot result shows the strength of feeling that remains on this issue. The union is committed to finding a solution which offers voluntary working and compensates those who do attend.
It will be the third successive Boxing Day walkout by Tube drivers in a dispute over Bank Holiday pay which dates back to an agreement in 1992.
The stoppage will disrupt Tube services on a busy day in the capital, causing chaos for shoppers, sports fans and visitors.
Talks have been held at the conciliation service Acas, but the dispute remains deadlocked.
