Johannes Hendrikus Jacob van den Berg (born 22 March 1946), better known as Harry Vanda, is a Dutch-Australian musician, songwriter and record producer. He is best known as lead guitarist of the 1960s Australian rock band the Easybeats who with fellow member George Young formed the 1970s and 1980s songwriting and record production duo Vanda & Young.

van den Berg is the last surviving member of the Easybeats, as of February 2025, following the death of the band's drummer, Gordon "Snowy" Fleet.

In September 2025, Vanda released his debut solo single "Devil Loose".

Johannes Hendrikus Jacob van den Berg was born in Voorburg, a town in the Province of South Holland in the Netherlands in 1946. His parents were Henricus Cornelius van den Berg (born 14 September 1923), a mechanic from the Netherlands and Lisa Berg-Warsozk (born 19 September 1924), who was Polish. Harry's parents got married on 9 June 1945. From 1942 to 1945, while Henricus was under forced labour under German rule during World War II.

Vanda's family migrated to Australia from the Netherlands in 1963, and settled in Sydney. In the same year, he met rhythm guitarist George Young at the Villawood migrant hostel. In 2007, Australian Musician magazine selected this meeting as the most significant event in Australian pop and rock music history.

Vanda, who had been a guitarist with the Hague-based band the Starfighters, came to fame in 1964–65 as the lead guitarist of the Easybeats.

Vanda's ability to speak English was still very limited when the band was at their peak. Easybeats bassist Dick Diamonde, who was also a Dutch Australian, would help him learn English. By 1966, Vanda was nearly fluent in English and he and George Young penned many of the Easybeats' later recordings, including their major international hit, "Friday On My Mind".

When I met Harry Vanda he could hardly speak a line of English and now he can speak it better than me - he teaches me words.
