The 30-year-old victim, who is Asian, was in Glasgow’s Gordon Street when he was assaulted shortly before midnight on Saturday.
The vicitm was approached by another man, who started shouting racist comments before attacking him, police said.
The victim was taken to hospital where he was treated for injuries to his face and shoulder.
Police are appealing for information and have issued a description of the suspect. He is described as white, around 6ft tall and of stocky build. He was wearing a light-coloured top.
Detective Constable Tony Brady said: “Since this incident was reported to police, officers have been carrying out inquiries in the local area and studying CCTV footage in an effort to gather more information on this crime and the man responsible.
“Gordon Street would have been busy with people on a night out and I would urge anyone who witnessed this crime, or has any information that may assist police enquiries, to contact police.”
The attack is the latest in a series of alleged hate crimes in Glasgow and Edinburgh in recent weeks.
Also on Saturday, a man was pushed to the ground and kicked in the face in a “brutal” homophobic attack in the capital.
The victim was walking with another man at 3:10am on Johnston Terrace, close to Edinburgh Castle, and heading towards the Lawnmarket area, when he was assaulted.
Officers said he was approached and verbally abused by three men, one of whom punched the victim to the ground before he and one of his companions kicked him several times in the face.
After the attack, the three men ran off and were chased by two passers-by into Castle Terrace, where they lost sight of them.
Police are still appealing for witnesses to help with the case.
BBC Scotland camera crews also captured a racist attack on a street busker while filming The Street, a documentary about life on Glasgow’s Sauchiehall Street.
Angolan-born singer Melo was called a “black b******” before the alleged suspect claimed he was “milking our country for thousands”, while he himself pays “hundreds of pounds [in taxes] to keep you in the f****** country”.
Graeme Pearson MSP, Labour’s shadow justice secretary, was among those to condemn the attack which was broadcast on the BBC show last week as “symptomatic of a culture we need to tackle, in terms of racism and sectarianism”.
It came days after a Scottish Government minister told The Scotsman how he was subject to alleged abuse outside Glasgow Queen Street while selling the Big Issue to raise awareness of those living on the streets.
The alleged abuse of Humza Yousaf MSP was also caught by a camera crew on 7 February. A 30-year-old has been arrested in connection with the incident.
And it followed another alleged racist assault earlier this month when four teenagers were held in connection with an attack in Edinburgh.
Two 18-year-olds were assaulted and their home was damaged by a group of youths in the Drylaw area.
Two males aged 16, a 15-year-old and a 17-year-old were arrested and have appeared in court.
