Betelgeuse and Rigel are the brightest stars in the Constellation. Even though Betelgeuse is designated Alpha Orionis, and Rigel is Beta Orionis, Rigel is almost always brighter than Betelgeuse. Rigel is a brilliant blue star that is relatively young, and Betelgeuse is a huge red star that if placed in our solar system would extend past the orbit of Mars!! That is a radius of more than 141 million miles

Betelgeuse is the bright reddish star at upper left, Rigel the bright star at lower right, Bellatrix the star to the right of center above the belt. Saiph is centered near the lower edge of the picture below the belt. Orion's head is marked by the trio of stars at the top of the picture just left of center, the brightest of which is Meissa. Mu Ori is just up and to the left of Betelgeuse. The the red glow in the middle of Orion's Sword is the Orion Nebula, which is lit by Theta-1 Ori. The multiple star Sigma Orionis is just down and to the rightof Alnitak, while Eta Orionis (Saif al Jabbar) is the second star down and to the right of Mintaka. To the upper right is a vertical string of stars all named Pi Orionis, from top to bottom Pi-3 (Tabit), Pi-4, Pi-5 (the one with a neighbbor), and Pi-6. Pi-1 and Pi-2 are off the top of the picture. W Ori is the second star down and to the left of Pi-6, while VV is the right-most star of the trio to the left of Alnilam. Orion's upraised club, topped by Chi-1 and Chi-2 Ori, rises off the picture at upper left; the two "Chi-stars" are visible on the images of both Gemini and Taurus. Betelgeuse is at the northwest apex of the Winter Triangle.

I'm betting that there are stars with intrinsic brightnesses brighter than Betelgeuse (alpha Orionis), and possibly brighter than Rigel (beta Orionis) and which lie within the boundaries of Orion. I'm also guessing that some of the stars within M-42 (the Great Nebula in Orion's sword) fit that criteria. It is their extreme distance that makes them seem dimmer. I'm also betting the question referred to apparent brightness, and not intrinsic brightness, so...nevermind.

Rigel and Betelgeuse. Betelgeuse is the reddish star above and to the left of the belt. Rigel is the bluish star below and to the right of the belt, (in the northern hemisphere.).
