Lee Oskar (born 24 March 1948) is a Danish harmonica player, notable for his contributions to the sound of the rock-funk fusion group War, which was formed by Howard E. Scott and Harold Brown, his solo work, and as a harmonica manufacturer. He continues to play with 3 other original War band members, Harold Brown, Howard Scott and B.B. Dickerson, under the name LowRider Band.

Born in Copenhagen, Denmark in 1948, Oskar was six years old when a family friend gave him his first harmonica. “I came from an area where every kid on the block had a harmonica”, he remembers. He grew up listening to Danish radio, enjoying all types of music and cites Ray Charles as the biggest influence from that period. When he was 17, Oskar decided that the United States was where a harmonica player should make his career. So he moved to New York at the age of 18 with little more than a harmonica in his pocket. With no money, Oskar played harmonica in the streets of New York. Eventually arriving in Los Angeles, via Toronto and San Francisco, Oskar soon met and joined forces with Eric Burdon who had recently disbanded The Animals and was searching for new collaborators.
