The party currently has the slenderest majority of one which it must defend on polling day – May 22.
Labour and the Conservatives will be contesting all 17 seats up for grabs and UKIP will be making a bold bid, fighting 10.
The Liberal Democrats are contesting four and the Independents and Greens three each.
There are no elections in the parishes as they are uncontested.
The existing Chorley Council line-up (47 seats in total) is Labour 24 councillors; Conservative 20; Independent Group 2; Coppull Independent one.
Former mayors of Chorley, Labour’s Alan Whittaker (Chisnall) and Independent Mel Coombes (Chorley East) will be attempting to return to the council.
And there could be a real family affair on the authority if Labour candidates, husband and wife Gordon and Margaret France succeed.
Their son Christopher France is a current Labour councillor for Wheelton and Withnell. He is portfolio champion for governance and families.
Gordon is standing in Pennine. Margaret, a former GP at the Wheelton Health Centre, is up for election in Wheelton and Withnell.
Former Lancashire county councillor for Chorley, Richard Toon, ex-chairman of the highways and transportation committee, is standing for Labour in Coppull.
Sitting stalwarts, Conservative Eric Bell, Clayton-le-Woods and Whittle-le-Woods and Independent Ralph Snape, Chorley North West, will be seeking to retain their seats.
