A man was stabbed in the face while another was knifed in the back and leg in two separate attacks over the weekend.
Gardai in Blanchardstown have launched two separate probes into the incidents in West Dublin on Saturday evening.
The first happened at around 4.30pm in the Parslickstown Drive area of Dublin 15.
A man, aged in his 40s, was attacked and was stabbed in the face.
The alarm was raised and he was rushed to Connolly Hospital in Blanchardstown.
Separately, and within a half an hour of the other attack, a man in his 30s was stabbed in the back and leg in Fortlawn Drive, Dublin 15.
The attacker is believed to have fled on foot.
He was also taken to hospital where he is being treated for his injuries.
The attacks are not linked to each other and two separate investigations are underway.
No arrests have been made as part of either probe.
A garda spokeswoman confirmed investigations into both incidents are ongoing.
