Y Byd ar Bedwar (Welsh for The World on Four) is a Welsh-language current affairs television programme, which has broadcast on S4C since the channel was launched in November 1982.

More recently, a series of undercover investigations into west Wales puppy farms have led to several pressure groups to call for a change in legislation by the Welsh Government to protect animals.
