Backing for Wales' first women's prison
Females represent just 5% of the overall prison population, with the total population standing at around 4,000.
But Welsh women serving jail sentences have to do so across the border in England.
The lack of a prison in Wales has long been an area of concern for family members as well as penal charities. S
peaking to reporters, Mr Jones welcomed news that north Wales was one of three candidate sights for a so-called new "super prison'' but would like to see a women's jail too.
He said: "People who are sentenced to custodial sentences in north Wales are often placed in prisons a long way away from where their families are and that's no good for them in terms of their rehabilitation. So, we are very supportive of the idea of a new prison being built in north Wales. It could have a significant potential for job creation. But there are no places for women in custody in Wales. I think a women's prison and a new prison in north of Wales are both needed.''
Previously, it has been claimed that Welsh women prisoners face isolation and neglect because they are "forced'' to serve time in English prisons.
Most Welsh female prisoners on remand will be detained at HMP Eastwood Park in Gloucestershire, while those serving longer sentences are usually sent as far afield as Derby or Surrey.
