Tenywa Bonseu (born October 28, 1976 in Kampala, Uganda) is a Ugandan soccer player, who currently plays defense for the Rochester Rhinos of the USL First Division.

Before becoming a professional, Bonseu played for Martin Methodist College of the NCAA Division II. He joined the Pittsburgh Riverhounds of the A-League in 1999 and played there for two seasons, before signing with the Major League Soccer's Chicago Fire for the stretch run. He has been in MLS since, with the Columbus Crew (2001), the Dallas Burn (2002-2003), and the MetroStars, who acquired Tenywa from Dallas for Steve Jolley before the 2004 season.

Scheduled to start at center back for the Metros, Bonseu was beaten out by rookie Jeff Parke and then moved to right back later in the year. In five seasons in MLS, Bonseu played in 87 regular season and 11 playoff games (starting all but three), but has never scored a goal. He was let go by the team after the year, and signed with Rochester.

Bonseu also plays for the Uganda national team, which he has represented 19 times.
