Professor Graham Virgo, Cambridge's senior pro-vice-Chancellor for education, said that the rise was partly down to a new scholarship for black students which was launched by the grime artist Stormzy a year ago.
While the university is crediting their own work for encouraging black students to apply, they acknowledge that Stormzy has had a vital role in facilitating low-income black students going to Cambridge - something they're dubbing the "Stormzy effect".
A record number of black students are studying at Cambridge university.
The university said it black undergraduates studying at Cambridge in total, a record number.
The inhabitants of black college students on the College of Cambridge has jumped by 50 per cent this 12 months, because of the "Stormzy effect"; 91 black college students began programs this autumn in comparison with exclusively 61 final 12 months.
It means 3.4 per cent of the 2,663 students enrolling in 2019 were black -up from 2.1 per cent in 2018. This figure makes up 7.9% of total acceptances on degree courses across the UK.
Over a quarter (26.8 per cent) of all undergraduates at Cambridge are now from black, Asian and minority ethnic backgrounds.
"The university has worked hard to get the message out that it is a welcoming place for students regardless of their ethnicity".
Cambridge said that after Stormzy made his offer in 2018, the university "has seen an increase in the number of black students engage in its outreach activities and enquire about its courses", leading to increasing numbers of applications.
It added that other factors include the involvement of several student societies in promoting the university of different groups of potential students, and proactive campaign work.
Wanipa Ndhlovu, President of the university's African-Caribbean Society, said: "This is really good news and is a testament to the hard work that ACS, as well as the University, has been putting in to break down perceptions".
His scholarship, alongside his outreach work, has sent clear signals to young black students that Cambridge is a place where they, too, can thrive.
David Lammy, the Labour MP for Tottenham, has been a frequent critic of the failure of Oxbridge colleges to admit students from diverse backgrounds.
