Yr Elen is a mountain in the Carneddau range in Snowdonia, Wales. It is the ninth highest mountain in Snowdonia. The average annual temperature of the peak is around 4 celsius. It lies on a short ridge running WNW off the main north-east to south-west ridge of the Carneddau, just over one kilometre from Carnedd Llewelyn.
It is usually climbed from the main ridge of the Carneddau, as it is only a short walk from Carnedd Llywelyn. It can also be climbed from Gerlan, near Bethesda, following Afon Llafar then heading up the slopes of Yr Elen, but this involves walking through wet valleys and a number of rivers that are difficult to cross.
