Odyssey is the fourth studio album by guitarist Yngwie Malmsteen, released on 8 April 1988 through Polydor Records. The album reached No. 40 on the US Billboard 200 and remained on that chart for eighteen weeks, as well as reaching the top 50 in five other countries. As of 2021, it remains Malmsteen's highest-charting release on the Billboard 200.
The album was released under the name "Yngwie J. Malmsteen's Rising Force." Jeff Glixman was brought in as producer, and his manager, Larry Mazer, who also managed Joe Lynn Turner, facilitated Turner's participation on the album as vocalist. During the production process, Yngwie faced several personal tragedies: on 22 June 1987 in Woodland Hills, Los Angeles, he crashed his Jaguar E-Type into a tree and remained in a coma for eight days, and in January 1988 he lost his mother, Rigmor, to cancer.
In terms of sales performance, the album ranked within the top 50 on the charts of nine countries. On the Billboard 200, it remained on the chart for eighteen weeks and reached a peak position of number 40, which, as of 2021, is the highest chart position achieved by any of Yngwie's releases.
Steve Huey at AllMusic gave Odyssey two stars out of five, calling it "a more subdued, polished collection seemingly designed for mainstream radio airplay", but that it "shows little difference in approach from [Malmsteen's] previous output". He praised Joe Lynn Turner's vocals and Malmsteen's guitar work, but remarked that the latter sounds "constrained and passionless" due in part to his recovery from a near-fatal car accident in 1987.
